Add config for Dell OptiPlex 3050 Micro

This is using Mate Kukri's port, which was added in
previous lbmk revisions. I've added an IFD that sets
the HAP bit, and unlocks regions as standard.

vcfg is set to 3050micro, which defines downloading
of the MEv11 image and it will run deguard automatically.

I made a small adjustment to vendor.sh, because the hotpatch
logic for deguard uses -C in git, and when doing that, the
specified directory path is relative to that Git repository;
the .patch path has been adjusted accordingly.

Also add 3rdparty/fsp to coreboot/default modules.

This board requires the ifdtool option: -p sklkbl

The -p option tells flashrom what quirks are present in a
given IFD. We don't normally need this on other Libreboot
targets that we currently support. The -p option was needed
for creating this modified IFD, and it is therefore needed in
the inject script. Therefore, an "IFD_platform" option is
specified in a given board's target.cfg file. If this is set,
another variable is set that makes -p be used.

In this case, 3050's target.cfg says:

IFD_platform="sklkbl"

This option enables quirks for skylake/kabylake descriptors,
as required when using ifdtool.

-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

-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).

+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.

+ "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 15/39] 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 18/39] mb/dell: Add Latitude E6530 (Ivy Bridge)
+
+Mainboard is QALA0/LA-7761P (UMA). The version with a Nvidia dGPU was
+not tested. I do not physically have this system; someone with physical
+access to one sent me the output of autoport which I then modified to
+produce this port.
+
+I was also sent the vbios obtained using intel_bios_dumper while running
+version A22 of the vendor firmware, which I then processed using
+`intelvbttool --inoprom vbios.bin --outvbt data.vbt` to obtain data.vbt.
+
+This was originally tested and found to be working as a standalone board
+port in Libreboot, though this variant based port in upstream coreboot
+has not been tested.
+
+This 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 19/39] mb/dell: Add Latitude E5530 (Ivy Bridge)
+
+Mainboard is QXW10/LA-7902P (UMA). I do not physically have this board;
+someone with physical access to one sent me the output of autoport which
+I then modified to produce this port. I was also sent the VBT binary,
+which was obtained from `/sys/kernel/debug/dri/0/i915_vbt` while running
+version A21 of the vendor firmware.
+
+This was originally tested and found to be working as a standalone board
+port in Libreboot, but this variant based port in upstream coreboot has
+not been tested.
+
+This 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 20/39] mb/dell: Add Latitude E6420 (Sandy Bridge)
+
+Mainboard is PAL50/LA-6591P (UMA). The version with an Nvidia dGPU was
+not tested. I do not physically have this system; someone with physical
+access to one sent me the output of autoport which I then modified to
+produce this port. I was also sent the VBT binary, which was obtained
+from `/sys/kernel/debug/dri/0/i915_vbt` while running version A25 of the
+vendor firmware.
+
+This was originally tested and found to be working as a standalone board
+port in Libreboot, but this variant based port in upstream coreboot has
+not been tested.
+
+This 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 21/39] mb/dell: Add Latitude E6520 (Sandy Bridge)
+
+Mainboard is PAL60/LA-6562P (UMA). The version with an Nvidia dGPU was
+not tested. I do not physically have this system; someone with physical
+access to one sent me the output of autoport which I then modified to
+produce this port. I was also sent the VBT binary, which was obtained
+from `/sys/kernel/debug/dri/0/i915_vbt` while running version A08 of the
+vendor firmware.
+
+This was originally tested and found to be working as a standalone board
+port in Libreboot, but this variant based port in upstream coreboot has
+not been tested.
+
+This 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 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
-the power LED while in S3. Without it, all LEDs turn off during S3.

+Subject: [PATCH 22/39] mb/dell: Add Latitude E5520 (Sandy Bridge)
+
+Mainboard is Krug 15". I do not physically have this system; someone
+with physical access to one sent me the output of autoport which I then
+modified to produce this port. I was also sent the VBT binary, which was
+obtained from `/sys/kernel/debug/dri/0/i915_vbt` while running version
+A14 of the vendor firmware.
+
+This was originally tested and found to be working as a standalone
+board port in Libreboot, but this variant based port in upstream
+coreboot has not been tested.
+
+This 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,

+Subject: [PATCH 23/39] mb/dell: Add Latitude E5420 (Sandy Bridge)
+
+Mainboard is Krug 14". I do not physically have this system; someone
+with physical access to one sent me the output of autoport which I then
+modified to produce this port. I was also sent the VBT binary, which was
+obtained from `/sys/kernel/debug/dri/0/i915_vbt` while running version
+A02 of the vendor firmware.
+
+This was originally tested and found to be working as a standalone board
+port in Libreboot, but this variant based port in upstream coreboot has
+not been tested.
+
+This 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 24/39] mb/dell: Add Latitude E6320 (Sandy Bridge)
+
+Mainboard is PAL70/LA-6611P. I do not physically have this system;
+someone with physical access to one sent me the output of autoport which
+I then modified to produce this port. I was also sent the VBT binary,
+which was obtained from `/sys/kernel/debug/dri/0/i915_vbt` while running
+version A22 of the vendor firmware. This port has not been tested.
+
+The EC is the SMSC MEC5055, which seems to be compatible with the
+existing MEC5035 code. As with the other Dell systems with this EC, this
+board is assumed to be internally flashable using an EC command that
+tells it to pull the FDO pin low on the next boot, which also tells the
+vendor firmware to disable all write protections to the flash [1].

+Subject: [PATCH 25/39] mb/dell: Add Latitude E6220 (Sandy Bridge)
+
+Mainboard is codenamed Vida. I do not physically have this system;
+someone with physical access to one sent me the output of autoport which
+I then modified to produce this port. The VBT was obtained using
+intelvbttool while running version A14 (latest available version) of the
+vendor firmware.
+
+Tested and found to boot as part of a libreboot build based on upstream
+coreboot commit b7341da191 with additional patches, though these do not
+appear to affect SNB/IVB. The base E6430 patch was tested against
+coreboot main.
+
+The EC is the SMSC MEC5055, which seems to be compatible with the
+existing MEC5035 code. As with the other Dell systems with this EC, this
+board is assumed to be internally flashable using an EC command that
+tells it to pull the FDO pin low on the next boot, which also tells the
+vendor firmware to disable all write protections to the flash [1].

+Subject: [PATCH 26/39] mb/dell: Add Latitude E6330 (Ivy Bridge)
+
+Mainboard is QAL70/LA-7741P. I do not physically have this system;
+someone with physical access to one sent me the output of autoport which
+I then modified to produce this port. I was also sent the VBT binary,
+which was obtained from `/sys/kernel/debug/dri/0/i915_vbt` while running
+version A21 of the vendor firmware. This port has not been tested.
+
+The EC is the SMSC MEC5055, which seems to be compatible with the
+existing MEC5035 code. As with the other Dell systems with this EC, this
+board is assumed to be internally flashable using an EC command that
+tells it to pull the FDO pin low on the next boot, which also tells the
+vendor firmware to disable all write protections to the flash [1].

+Subject: [PATCH 27/39] mb/dell: Add Latitude E6230 (Ivy Bridge)
+
+This was adapted from CB:22693 from Iru Cai, which was based on
+autoport. I do not physically have this system. Someone with physical
+access to an E6230 running version A11 of the vendor firmware sent me
+the VBT after running the command `intelvbttool --inlegacy --outvbt
+data.vbt`. This new version of the port has not yet been tested.
+
+The EC is the SMSC MEC5055, which seems to be compatible with the
+existing MEC5035 code. As with the other Dell systems with this EC, this
+board is assumed to be internally flashable using an EC command that
+tells it to pull the FDO pin low on the next boot, which also tells the
+vendor firmware to disable all write protections to the flash [1].

-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

-Subject: [PATCH 29/48] src/intel/skylake: Disable stack overflow debug options
-
-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.

-
-Build systems like lbmk need to reproducibly insert

-
-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

-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.

-+	  along with config/vendor/*/pkg.cfg entries defining a URL to the

-+	  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

-+	  can flash the TB firmware while flashing Libreboot firmware. Easy!

-+	  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

-
-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 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 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 44/48] topton x2e n150: use old fsp
-
-i added the old fsp back, so that we didn't have to
-mess around with vendor files in lbmk, because coreboot
-upstream updated the fsp repo, which modified this
-fsp file.
-
-we know the old fsp worked. there's no point testing
-the new one yet, unless someone can tell me about
-real bugs that got fixed.

+Subject: [PATCH 05/17] 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 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.

-Subject: [PATCH] mb/supermicro/x11-lga1151-series: Enable SATA hotplug
-
-Before this patch, hotplugging only worked to replace drives (if you
-tried to plug a drive into a SATA port that no drive was plugged in to
-at boot, it wouldn't be detected) and you'd have to manually rescan
-the bus (echo "- - -" > /sys/class/scsi_host/host*/scan) to make
-plugs/unplugs get detected by the operating system.
-
-Now, hotplugging works for all ports (tested and working on Supermicro
-X11SSH-LN4F) and there's no need to manually rescan (it sometimes
-takes a few seconds for unplugs to be detected, but plugs are detected
-instantly).

+Subject: [PATCH 12/17] haswell NRI: Add function to change margins
+
+Implement a function to change margin parameters. Haswell provides a
+register to apply an offset to margin parameters during training, so
+make use of it. There are other margin parameters that have not been
+implemented yet, as they are not needed for now and special handling
+is needed to provide offset training functionality.
