Add 9020 SFF/MT configs using native raminit

Angel's code was rebased for coreboot/default, so it's now feasible to have NRI configs for these. NRI is incomplete, because some training steps are still not implemented and S3 is not yet supported, so Libreboot still provides the MRC setups as default options, but the NRI is nicer to use if it works for you (and you don't need S3). In Libreboot the policy is always: use fewer blobs if possible. Signed-off-by: Leah Rowe <leah@libreboot.org>

-Libreboot provides 
-[libre](https://libreboot.org/freedom-status.html)
-boot firmware on
-[supported motherboards](https://libreboot.org/docs/install/#which-systems-are-supported-by-libreboot). It replaces proprietary vendor BIOS/UEFI implementations, by
-* Using coreboot to initialize the hardware (e.g. memory controller, CPU, etc.) while
-  minimizing unwanted functionality (e.g. backdoors such as the Intel Management Engine)
-* ... which runs a payload such as SeaBIOS, GRUB, or U-Boot
-* ... which loads your operating system's boot loader (BSD and Linux-based
-  [systems](systems) are supported).
+The `libreboot` project provides
+[libre](https://libreboot.org/freedom-status.html) *boot
+firmware* that initializes the hardware (e.g. memory controller, CPU,
+peripherals) on specific Intel/AMD x86 and ARM targets, which
+then starts a bootloader for your operating system. Linux/BSD are
+well-supported. It replaces proprietary BIOS/UEFI firmware. Help is available
+via [\#libreboot IRC](https://web.libera.chat/#libreboot)

-Why use Libreboot, and what is coreboot?
----------------------------------------
+Why use Libreboot?
+==================

-A lot of users who use libre operating systems still use proprietary boot
-firmware, which often contain backdoors and bugs, hampering
-[user freedom](https://writefreesoftware.org) and
-[right to repair](https://www.eff.org/issues/right-to-repair).
+Why should you use *libreboot*?
+----------------------------

-[coreboot](https://coreboot.org) provides libre boot firmware by initializing
-the hardware then running a payload. However, coreboot is notoriously difficult
-to configure and install for most non-technical users, requiring detailed
-technical knowledge of hardware.
+Libreboot gives you freedoms that you otherwise can't get with most other
+boot firmware. It's extremely powerful and configurable for many use cases.

-Libreboot solves this by being **a coreboot distribution** (in the same way
-that Alpine Linux is a Linux distribution). It provides a fully automated build
-system that downloads and compiles pre-configured ROM images for supported
-motherboards, so end-users could easily fetch images to flash onto their
-devices.
+You have rights. The right to privacy, freedom of thought, freedom of speech
+and the right to read. In this context, Libreboot gives you these rights.
+Your freedom matters.
+[Right to repair](https://vid.puffyan.us/watch?v=Npd_xDuNi9k) matters.
+Many people use proprietary (non-libre)
+boot firmware, even if they use [a libre OS](https://www.openbsd.org/).
+Proprietary firmware often contains backdoors (more info on the FAQ), and it
+and can be buggy. The libreboot project was founded in December 2013,
+with the express purpose of making coreboot firmware accessible for
+non-technical users.

-Libreboot also produces documentation aimed at non-technical users and
-excellent user support via IRC.
+The `libreboot` project uses [coreboot](https://www.coreboot.org/) for [hardware
+initialisation](https://doc.coreboot.org/getting_started/architecture.html).
+Coreboot is notoriously difficult to install for most non-technical users; it
+handles only basic initialization and jumps to a separate
+[payload](https://doc.coreboot.org/payloads.html) program (e.g.
+[GRUB](https://www.gnu.org/software/grub/),
+[Tianocore](https://www.tianocore.org/)), which must also be configured.
+*The libreboot software solves this problem*; it is a *coreboot distribution* with
+an automated build system (named *lbmk*) that builds complete *ROM images*, for
+more robust installation. Documentation is provided.

-Contribute
----------
+How does Libreboot differ from coreboot?
+========================================
+
+In the same way that *Debian* is a GNU+Linux distribution, `libreboot` is
+a *coreboot distribution*. If you want to build a ROM image from scratch, you
+otherwise have to perform expert-level configuration of coreboot, GRUB and
+whatever other software you need, to prepare the ROM image. With *libreboot*,
+you can literally download from Git or a source archive, and run `make`, and it
+will build entire ROM images. An automated build system, named `lbmk`
+(Libreboot MaKe), builds these ROM images automatically, without any user input
+or intervention required. Configuration has already been performed in advance.
+
+If you were to build regular coreboot, without using libreboot's automated
+build system, it would require a lot more intervention and decent technical
+knowledge to produce a working configuration.
+
+Regular binary releases of `libreboot` provide these
+ROM images pre-compiled, and you can simply install them, with no special
+knowledge or skill except the ability to follow installation instructions
+and run commands BSD/Linux.
+
+Project goals
+=============
+
+-   *Support as much hardware as possible!* Libreboot aims to eventually
+    have *maintainers* for every board supported by coreboot, at every
+    point in time.
+-   *Make coreboot easy to use*. Coreboot is notoriously difficult
+    to install, due to an overall lack of user-focused documentation
+    and support. Most people will simply give up before attempting to
+    install coreboot. Libreboot's automated build system and user-friendly
+    installation instructions solves this problem.
+
+Libreboot attempts to bridge this divide by providing a build system
+automating much of the coreboot image creation and customization.
+Secondly, the project produces documentation aimed at non-technical users.
+Thirdly, the project attempts to provide excellent user support via IRC.
+
+Libreboot already comes with a payload (GRUB), flashprog and other
+needed parts. Everything is fully integrated, in a way where most of
+the complicated steps that are otherwise required, are instead done
+for the user in advance.
+
+You can download ROM images for your libreboot system and install
+them without having to build anything from source. If, however, you are
+interested in building your own image, the build system makes it relatively
+easy to do so.
+
+Not a coreboot fork!
+--------------------
+
+Libreboot is not a fork of coreboot. Every so often, the project
+re-bases on the latest version of coreboot, with the number of custom
+patches in use minimized. Tested, *stable* (static) releases are then provided
+in Libreboot, based on specific coreboot revisions.
+
+How to help
+===========

 You can check bugs listed on
 the [bug tracker](https://codeberg.org/libreboot/lbmk/issues).

-You may use Codeberg pull requests to send patches with bug fixes or other
-improvements. This repository hosts the code for the main build system.
-The website lives in [a separate repository](https://codeberg.org/libreboot/lbwww).
+If you spot a bug and have a fix, the website has instructions for how to send
+patches, and you can also report it. Also, this entire website is
+written in Markdown and hosted in a [separate
+repository](https://codeberg.org/libreboot/lbwww) where you can send patches.

-Development is also done on the IRC channel.
+Any and all development discussion and user support are all done on the IRC
+channel. More information is on <https://libreboot.org/contact.html>.

+Subject: [PATCH 1/1] cbfstool: Make use of spurious null-termination
+
+The null-termination of `filetypes` was added after the code was
+written, obviously resulting in NULL dereferences. As some more
+code has grown around the termination, it's hard to revert the
+regression, so let's update the code that still used the array
+length.
+
+This fixes commit 7f5f9331d1 (util/cbfstool: fix buffer over-read)
+which actually did fix something, but only one path while it broke
+two others. We should be careful with fixes, they can always break
+something else. Especially when a dumb tool triggered the patching
+it seems likely that fewer people looked into related code.

+Subject: [PATCH 13/30] lenovo/x230: introduce FHD variant
+
+There is a modification for the x230 which uses the 2nd DP from the dock
+as the integrated panel's connection, which allows using a custom eDP
+panel instead of the stock LVDS display.
+
+There are several adapter boards present on the market and all of them
+uses the same method of enabling the custom eDP panel.
+
+To make this work with coreboot, the internal LVDS connector should be
+disabled in libgfxinit. The VBT has been modified as well, which allows
+brightness controls to work out of the box.
+
+The modifications done to the VBT are:
+- Remove the LVDS port entry.
+- Move the DP-3 (which is the 2nd DP on the dock) entry to the first
+  position on the list.
+- Set the DP-3 as internally connected.
+
+This has been reported to work with the following panels:
+- LP125WF2-SPB4 (1920*1080, 12.5")
+- LQ125T1JW02 (2560*1440, 12.5")
+- LQ133M1JW21 (1920*1080, 13.3")
+- LTN133HL10-201 (1920*1080, 13.3")
+- B133HAN04.6 (1920*1080, 13.3")
+- B133QAN02.0 (2560*1600, 13.3")
+
+Other eDP panels not on this list should work as well.

-Subject: [PATCH 14/48] ec/dell/mec5035: Add S3 suspend SMI handler
-
-This is necessary for S3 resume to work on SNB and newer Dell Latitude
-laptops. If a command isn't sent, the EC cuts power to the DIMMs,
-preventing the system from resuming. These commands were found using an
-FPGA to log all LPC bus transactions between the host and the EC and
-then narrowing down which ones were actually necessary.
-
-Interestingly, the command IDs appear to be identical to those in
-ec/google/wilco, the EC used on Dell Latitude Chromebooks, and that EC
-implements a similar S3 SMI handler as the one implemented in this
-commit. The Wilco EC Kconfig does suggest that its firmware is a
-modified version of Dell's usual Latitude EC firmware, so the
-similarities seem to be intentional.
-
-These similarities also identified a command to enable or disable wake
-sources like the power button and lid switch, and this was added to the
-SMI handler to disable lid wake as the system does not yet resume
-properly from a like wake with coreboot.
-
-Tested on the Latitude E6430 (Ivy Bridge) and the Precision M6800
-(Haswell, not yet pushed).

-Subject: [PATCH 15/48] nb/haswell: lock policy regs when disabling IOMMU
-
-Angel Pons told me I should do it. See comments here:
-https://review.coreboot.org/c/coreboot/+/81016
-
-I see no harm in complying with the request. I'll merge
-this into the main patch at a later date and try to
-get this upstreamed.
-
-Just a reminder: on Optiplex 9020 variants, Xorg locks up
-under Linux when tested with a graphics card; disabling
-IOMMU works around the issue. Intel graphics work just fine
-with IOMMU turned on. Libreboot disables IOMMU by default,
-on the 9020, so that users can install graphics cards easily.

+ "cpu/intel/model_1067x: enable PECI"
+
+This reverts commit 70fea013c7ebd6d85a7806748233fcfd76802f5f.
+
+Enabling PECI without microcode updates loaded causes the CPUID feature set
+to become corrupted. And one consequence is broken SpeedStep. At least, that's
+my understanding looking at Intel Errata. This revert is not a fix, because
+upstream is correct (upstream assumes microcode updates). We will simply
+maintain this revert patch in Libreboot, from now on.

+Subject: [PATCH 17/30] GM45-type CPUs: don't enable alternative SMRR
+
+This reverts the changes in coreboot revision:
+df7aecd92643d207feaf7fd840f8835097346644
+
+While this fix is *technically correct*, the one in
+coreboot, it breaks rebooting as tested on several
+GM45 ThinkPads e.g. X200, T400, when microcode
+updates are not applied.
+
+Since November 2022, Libreboot includes microcode
+updates by default, but it tells users how to remove
+it from the ROM (with cbfstool) if they wish.
+
+Well, with Libreboot 20221214, 20230319 and 20230413,
+mitigations present in Libreboot 20220710 (which did
+not have microcode updates) do not exist.
+
+This patch, along with the other patch to remove PECI
+support (which breaks speedstep when microcode updates
+are not applied) have now been re-added to Libreboot.
+
+It is still best to use microcode updates by default.
+These patches in coreboot are not critically urgent,
+and you can use the machines with or without them,
+regardless of ucode.
+
+I'll probably re-write this and the other patch at
+some point, applying the change conditionally upon
+whether or not microcode is applied.
+
+Pragmatism is a good thing. I recommend it.

-Subject: [PATCH 17/48] nb/gm45: Fix Angel's DDR2 RCOMP fix on DDR3 boards
-
-We add this patch:
-
-commit commit_id_here
-Author: Angel Pons <th3fanbus@gmail.com>
-Date:   Mon May 10 22:40:59 2021 +0200

-    nb/intel/gm45: Make DDR2 raminit work
-
-This patch was original applied, in lbmk, only on coreboot/dell,
-separately from coreboot/default, which was wasteful because it
-meant having an entire coreboot tree just for a single board. We
-did this, because the DDR2 RCOMP fix happened to break DDR3 init
-on other boards.
-
-What *this* new patch does on top of Angel's patch, is make sure
-that their changes only apply to DDR2, while DDR3 behaviour remains
-unchanged. This means that the Dell Latitude E6400 can be supported
-in the main coreboot tree, within lbmk.
-
-Essentially, this patch restores the old behaviour, prior to applying
-Angel's patch, only when DDR3 memory is used.

-Subject: [PATCH 18/48] mb/dell/e6400: Use 100 MHz reference clock for display
-
-The E6400 uses a 100 MHz reference clock for spread spectrum support on
-LVDS, whereas libgfxinit previously assumed a 96 MHz input clock. For
-the more common 1280 x 800 display panels, the numerical error was not
-large enough to cause noticable issues, but the actual pixel clock
-frequency derived from a 100 MHz reference using PLL configs calculated
-assuming a 96 MHz reference was not close enough for 1440 x 900 panels,
-which require a much higher pixel clock. This resulted in a garbled
-display in the pre-OS graphics environment provided by libgfxinit.

-Subject: [PATCH 19/48] nb/x4x: define INTEL_GMA_DPLL_REF_FREQ
-
-set it to 96MHz. fixes the following build error when
-building for x4x boards e.g. gigabyte ga-g41m-es2l:
-
-hw-gfx-gma-plls.adb:465:46: error: "INTEL_GMA_DPLL_REF_FREQ" not declared in "Config"
-make: *** [Makefile:423: build/ramstage/libgfxinit/common/g45/hw-gfx-gma-plls.o] Error 1
-
-this error was introduced when merging coreboot/dell
-into coreboot/default in lbmk. nicholas chin's fix in lbmk
-was as follows:
-
-commit 8629873a6043067affc137be275b7aa69cb1f10c
-Author: Nicholas Chin <nic.c3.14@gmail.com>
-Date:   Mon May 20 10:46:25 2024 -0600
-
-    Fix E6400 display issue with 1440 x 900 panel
-
-this currently corresponds to the patch in lbmk,
-as of 12 august 2024:
-
-0042-mb-dell-e6400-Use-100-MHz-reference-clock-for-displa.patch
-
-The assumption prior to Nicholas's fix was 96MHz, so set
-it accordingly on x4x northbridge.

+Subject: [PATCH 20/30] mb/dell: Add Latitude E6430 (Ivy Bridge)
+
+Mainboard is QAL80/LA-7781P (UMA). The dGPU model was not tested. This
+is based on the autoport output with some manual tweaks. The flash is
+8MiB + 4MiB, and is fairly easily accessed by removing the keyboard. It
+can also be internally flashed by sending a command to the EC, which
+causes the EC to pull the FDO pin low and the firmware to skip setting
+up any chipset based write protections [1]. The EC is the SMSC MEC5055,
+which seems to be compatible with the existing MEC5035 code.
+
+Working:
+- Libgfxinit
+- USB EHCI debug (left side usb port is HCD index 2, middle port on the
+  right side is HCD index 1)
+- Keyboard
+- Touchpad/trackpoint
+- ExpressCard
+- Audio
+- Ethernet
+- SD card reader
+- mPCIe WiFi
+- SeaBIOS 1.16.2
+- edk2 (MrChromebox' fork, uefipayload_202306)
+- Internal flashing using dell-flash-unlock
+
+Not working:
+- S3 suspend: Possibly EC related
+- Physical wireless switch - this triggers an SMI handler in the vendor
+  firmware which sends commands to the EC to enable/disable wireless
+  devices
+- Battery reporting - needs ACPI code for the EC
+- Brightness hotkeys - probably EC related
+
+Unknown/untested:
+- Dock
+- eSATA
+- TPM
+- dGPU on non-UMA model
+- Bluetooth module (not included on my system)

-Subject: [PATCH 21/48] mb/dell: Add S3 SMI handler for Dell Latitudes
-
-Integrate the previously added mec5035_smi_sleep() function into
-mainboard code to fix S3 suspend on the SNB/IVB Latitudes and the E7240.
-The E6400 does not require the EC command to sucessfully suspend and
-resume from S3, though sending it does enable the breathing effect on

-Subject: [PATCH 22/48] Disable compression on refcode insertion
-
-Compression is not reliably reproducible. In an lbmk release
-context, this means we cannot rely on vendorfile insertion.
-
-Therefore, use uncompressed refcode.

+Subject: [PATCH 22/30] don't use github for the acpica download
+
+i have the tarball from a previous download, and i placed
+it on libreboot rsync, which then got mirrored to princeton.
+
+today, github's ssl cert was b0rking the hell out and i really
+really wanted to finish a build, and didn't want to wait for
+github to fix their httpd.
+
+so i'm now hosting this specific acpica tarball on rsync.
+
+this patch makes that URL be used, instead of the github one.
+
+that's the 2nd time i've had to patch coreboot's acpica download!

+Subject: [PATCH 26/30] mb/dell: Add Latitude E6530 (Ivy Bridge)
+
+Mainboard is QALA0/LA-7761P (UMA). The dGPU model was not tested.  This
+is based on the autoport output with some manual tweaks. The flash is
+8MiB + 4MiB. It can be internally flashed by sending a command to the
+EC, which causes the EC to pull the FDO pin low and the firmware to skip
+setting up any chipset based write protections. [1] The EC is the SMSC
+MEC5055, which seems to be compatible with the existing MEC5035 code.

-Subject: [PATCH 28/48] dell/3050micro: disable nvme hotplug
-
-in my testing, when running my 3050micro for a few days,
-the nvme would sometimes randomly rename.
-
-e.g. nvme0n1 renamed to nvme0n2
-
-this might cause crashes in linux, if booting only from the
-nvme. in my case, i was booting from mdraid (sata+nvme) and
-every few days, the nvme would rename at least once, causing
-my RAID to become unsynced. since i'm using RAID1, this was
-OK and I could simply re-sync the array, but this is quite
-precarious indeed. if you're using raid0, that will potentially
-corrupt your RAID array indefinitely.
-
-this same issue manifested on the T480/T480 thinkpads, and
-S3 resume would break because of that, when booting from nvme,
-because the nvme would be "unplugged" and appear to linux as a
-new device (the one that you booted from).
-
-the fix there was to disable hotplugging on that pci-e slot
-for the nvme, so apply the same fix here for 3050 micro

-The option was appearing in T480/3050micro configs of lbmk,

-
-CONFIG_DEBUG_STACK_OVERFLOW_BREAKPOINTS=y

-
-    soc/intel/pantherlake: Disable stack overflow debug options
-
-Well now:
-
-I'm disabling this behaviour on Skylake, for the same
-behaviour, because I want as few behaviour changes in general,
-as possible, for the rev8 release.
-
-According to Subrata's patch, which was for Pantherlake,
-without this change, stack corruption can occur on verstage
-and romstage early on. Please look at that coreboot patch,
-referenced above, for clarity.
-
-I see no harm in disabling this option for Skylake, since
-the behaviour that it otherwise enables was not present
-before.

-Subject: [PATCH 30/48] soc/intel/skylake: Don't compress FSP-S
-
-Build systems like lbmk need to reproducibly insert
-certain vendor files on release images.
-
-Compression isn't always reproducible, and making it
-so costs a lot more time than simply disabling compression.
-
-With this change, the FSP-S module will now be inserted
-without compression, which means that there will now be
-about 40KB of extra space used in the flash.

-Subject: [PATCH 31/48] lenovo: Add Kconfig option CONFIG_LENOVO_TBFW_BIN
-
-This is used by lbmk to know where a tb.bin file goes,
-when extracting and padding TBT.bin from Lenovo ThunderBolt
-firmware updates on T480/T480s and other machines, grabbing
-Lenovo update files.
-
-Not used in any builds, so it's not relevant for ./mk inject
-
-However, the ThunderBolt firmware is now auto-downloaded on
-T480/T480s. This is not inserted, because it doesn't go in
-the main flash, but the resulting ROM image can be flashed
-on the TB controller's separate flash chip.
-
-Locations are as follows:
-
-vendorfiles/t480s/tb.bin
-vendorfiles/t480/tb.bin
-
-This can be used for other affected ThinkPads when they're
-added to Libreboot, but note that Lenovo provides different
-TB firmware files for each machine.
-
-Since I assume it's the same TB controller on all of those
-machines, I have to wonder: what difference is there between
-the various TBT.bin files provided by Lenovo, and how do they
-differ in terms of actual flashed configuration?
-
-We simply flash the padded TBT.bin when updating the firmware,
-flashing externally. That's what this patch is for, so that
-lbmk can auto-download them.

-+	  lbmk can be flashed to the ThunderBolt firmware's 25XX NOR device.
-+	  Earlier versions of this firmware had debug commands enabled that
-+	  sent logs to said flash IC, and it would quickly fill up, bricking
-+	  the ThunderBolt controller. With these updates, flashed externally,
-+	  you can fix the issue if present or otherwise prevent it. The benefit
-+	  here is that you then don't need to use Windows or a boot disk. You
-+	  can flash the TB firmware while flashing Libreboot firmware. Easy!
-+	  Look for these variables in lbmk:
-+	  TBFW_url TBFW_url_bkup TBFW_hash and look at how it handles that and
-+	  CONFIG_LENOVO_TBFW_BIN, in lbmk's include/vendor.sh file.
-+	  The path set by CONFIG_LENOVO_TBFW_BIN is used by lbmk when extracting
-+	  the firmware, putting it at that desired location. In this way, lbmk
-+	  can auto-download such firmware. E.g. ./mk -d coreboot t480_fsp_16mb
-+	  and it appears at vendorfiles/t480/tb.bin fully padded and everything!
-+
-+	  Just leave this blank if you don't care about this option. It's not
-+	  useful for every ThinkPad, only certain models.

+Subject: [PATCH 1/1] mb/dell: Add OptiPlex 7020/9020 port
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The OptiPlex 7020 and 9020 use physically identical motherboards.
+
+Each model comes in the following form factors:
+- 7020: SFF, MT
+- 9020: USFF (not currently supported), SFF, MT
+
+(7020 SFF) Boots Linux and Windows 10:
+- Tested with an i3-4160 and i5-4460
+- DRAM init works using the MRC (4G, 4G+4G)
+- iGPU init works using libgfxinit (VGA, 2x DP)
+- PCIe 16x: tested, ok
+- PCIe 4x: tested, ok
+- All USB2 and USB3 ports work
+- SMSC SCH5555 Super I/O: serial works, PS/2 untested
+- Audio: back and front output works, internal speaker works,
+         mic inputs untested
+- Ethernet: tested, works
+
+(9020 MT)
+- Tested by Michael Büchler (thanks for the overridetree)

-Subject: [PATCH 33/48] soc/intel/alderlake: Disable
- MRC_CACHE_USING_MRC_VERSION
-
-There's some issue with building against the FSP headers in src/vendorcode.
-Headers in 3rdparty/fsp work, but since FspProducerDataHeaer.h is missing
-from there, we need to disable MRC_CACHE_USING_MRC_VERSION by force.

-Subject: [PATCH 34/48] Subject: [PATCH 1/1] Add a -p option (skip FPTR checks)
-
-if you pass -k (keep fptr modules), don't use -r, don't
-use -t, you can essentially just use me_cleaner to
-extract a ME image without changing it. this is useful
-when for example, you just want to set the HAP bit.
-
-however, me_cleaner still performs a FPTR check.
-
-on some newer ME versions, it's always invalid according
-to me_cleaner, because for example it doesn't handle
-ME16 very well yet.
-
-this patch adds an option to override the FPTR check
-
-either pass -p or --pass-fptr
-
-NOTE: we probably won't use this on coreboot's me_cleaner,
-which is the corna version. we only need it on the newer
-me_cleaner versions for e.g. ME16, on certain setups.
-still, it's best to have the patch here too, just in case.

-Subject: [PATCH 35/48] soc/intel/alderlake: Don't compress FSP-S
-
-Build systems like lbmk need to reproducibly insert
-certain vendor files on release images.
-
-Compression isn't always reproducible, and making it
-so costs a lot more time than simply disabling compression.
-
-With this change, FSP-S uses slightly more space inside
-the flash, but it's not that much.

-Subject: [PATCH 38/48] ec/dell/mec5035: Add command to disable EC-initiated
- thermal shutdown
-
-If command 0xBF isn't sent, the EC shuts down the system without warning
-as soon as the CPU temperature reaches about 87 degrees, without letting
-the CPU thermal throttle to try and reduce the temperature. With vendor
-firmware, the CPU is able to reach around 100 degrees before thermal
-throttling.
-
-This command was found by collecting EC commands by logging the LPC bus
-while running with vendor firmware and then replaying observed commands
-from coreboot. By systematically replaying subsets of commands in a
-binary search pattern and then stress testing the system, the command to
-disable the shutdown was isolated.
-
-The exact meaning of the parameters for this command are unknown at this
-time, but do seem to differ between different generations of these
-laptops. Due to this, the commmand should be called by mainboard
-specific code which passes the specific parameter value used.
-
-The Google Wilco EC code, which runs on Latitude Chromebooks and shares
-many commands with the standard Latitude ECs, suggests that command 0xBF
-tells the EC about the processors CPUID. However, the values observed in
-LPC bus logs do not seem to correspond with any CPUID values on the
-non-Chromebook systems I tested.
-
-Observed command parameter values (sent on mailbox registers 2-4):
- E6430 (Ivy Bridge): 0x07, 0x00, 0x00
- M6800 (Haswell): 0x14, 0x00, 0x00

+Subject: [PATCH 1/1] fix sata ports on dell 9020 sff and mt
+
+mate kukri has a patch under review on coreboot that sets
+sata port map to 0x7 on sff and 0xf on mt.
+
+see: intel 8 series pch datasheet, section 13.1.35
+
+basically, the 6 least significant bits enable the sata
+slots; 1 for enable and 0 for disable. there can be up
+to 6 ports. least significant bit is port 0, then next
+is port 1, and so on.
+
+coreboot currently enables ports 0, 1, 4 and 5, making this
+value 0x33 (converted to binary: 00110011). sff has ports
+0, 1 and 2 wired, so mate changed that to 0x7 (00000111).
+
+on mt, the blue ports are ports 0 and 1, but the two white
+ports don't work, but coreboot enables 4 and 5; it is
+likely that the blue ports are in fact 0 and 1, and the
+white ports are 2 and 3, but we've not tested this!
+
+it could be that the blue ports are ports 4 and 5, and
+the white ports are 2 and 3! we have not yet determined
+this, but mate set it to 0xf, meaning ports 0 1 2 and 3
+are enabled, in his patch under review. the chance that
+it's 2, 3, 4 and 5 on the board is unlikely, but it is
+theoretically possible and has not been confirmed.
+
+therefore, for now, i will set the value to 0x3f, which
+in binary is 00111111, thus enabling all 6 slots. the two
+that aren't physically wired don't really matter. enabling
+ports (from the pch) that electrically aren't there and
+then powering on is electrically equivalent to those ports
+being actually being wired, but with no devices plugged
+into them. therefore, 0x3f is an effective shotgun fix.
+
+i'll remove this patch and use mate's fix when the latter
+has been tested on MT; it has already been tested on SFF.
+
+this patch fixes the 3rd sata slot on 9020 sff, and the 3rd
+and 4th sata slots on 9020 MT

+Subject: [PATCH 1/1] nb/haswell: Disable iGPU when dGPU is used
+
+This is usually is handled by Haswell mrc.bin, disabling VGA
+decode on the iGPU when a dGPU is installed. However, Broadwell
+mrc.bin does not, so the iGPU and dGPU are both enabled.
+
+This patch disables legacy VGA cycles for iGPU, under such
+conditions. It has been tested on Broadwell mrc.bin when
+using a graphics card on Dell OptiPlex 9020 SFF (currently
+under review at this time of writing, submitted by Mate
+Kukri).
+
+This patch has also been tested when Haswell mrc.bin is used,
+and there are seemingly no breaking changes caused by it.

+Subject: [PATCH 1/1] mb/dell/optiplex_9020: Implement late HWM initialization
+
+There are 4 different chassis types specified by vendor firmware, each
+with a slightly different HWM configuration.
+
+The chassis type to use is determined at runtime by reading a set of
+4 PCH GPIOs: 70, 38, 17, and 0.
+
+Additionally vendor firmware also provides an option to run the fans at
+full speed. This is substituted with a coreboot nvram option in this
+implementation.
+
+This was tested to make fan control work on my OptiPlex 7020 SFF.
+
+NOTE: This is superficially similar to the OptiPlex 9010's SCH5545
+however the OptiPlex 9020's SCH5555 does not use externally
+programmed EC firmware.

+Subject: [PATCH 01/15] haswell NRI: Initialise MPLL
+
+Add code to initialise the MPLL (Memory PLL). The procedure is similar
+to the one for Sandy/Ivy Bridge, but it is not worth factoring out.

-

+Subject: [PATCH 05/15] haswell NRI: Program memory map
+
+This is very similar to Sandy/Ivy Bridge, except that there's several
+registers to program in GDXCBAR. One of these GDXCBAR registers has a
+lock bit that must be set in order for the memory controller to allow
+normal access to DRAM. And it took me four months to realize this one
+bit was the only reason why native raminit did not work.

-Subject: [PATCH 47/48] me_cleaner: don't modify if -k is used
-
-don't remove *anything*. in libreboot, we only
-ever use -k when we werely want to extract the
-ME, but otherwise not modify it. this is because
-we rely on bruteforce, detecting when me.bin is
-found based on mecleaner validation.
-
-this way, we can much more reliable get the ME
-images.

-Subject: [PATCH 48/48] mb/lenovo/sklkbl: Add Lenovo Thinkpad X270 as a variant
-
-This machine is somewhat dissimilar from the X280 in the PCIe allocations in the overridetree. It also lacks soldered RAM, having a single SODIMM slot.
-
-This port was based upon the work done by Johann C Rode for the X280 and the VBT and hda verbs were obtained from that work, not obtained separately. GPIO ports and PCI-e allocations have been checked against schematics after editing.
-
-Functionality has been validated on a ThinkPad X270 with machine type model 20HMS2WU03 with 16GB onboard RAM and i5-7300U CPU. The laptop has been tested running libreboot, booting Guix via GRUB payload. A check of the hardware shows no issues (video, wifi, wired ethernet, reboot, sleep, NVMe).
-
-An untested variety allowing for a Skylake CPU (for 20K5 and 20K6) has been included.
