Specifically, use the same revision that Mate used in patchset 15.
This will ensure that any issues are *not* caused by the coreboot
revision; this is being done, because the old coreboot revision was
from July, but patchset 15 from Mate is based on a September revision
of coreboot.
I've been eliminating as many variables as possible, trying to fix
SeaBIOS payload on this machine, because it hangs in Libreboot, but
not when building from gerrit directly, which means the coreboot
revision may be a factor (since I'm using his patches on an older
revision so upstream might have made some changes since then that
the port relies on).
For this, a new coreboot tree is used, called "dell7", referring to
the fact that Kabylake is Intel's 7th generation.

Add patches to convert the E6400 port into a GM45 Latitude variant and
add the E4300 as another variant, and create a config for the E4300.
Tested on my E6400 and E4300.

I ran ./mk -u coreboot, to update existing configs
after merging. Actualy IFD and coreboot configs will
be done in the next revision. I've already added logic
for handling deguard, in preparation for this.

The libgfxinit patch and other patches e.g. DDR2 fix, are
now provided in coreboot/default. The Latitude E6400 is now
using the newer coreboot revision from late July 2024.
Some other configs had to change because of this, relating to
the new way that Nicholas handles timing on LVDS displays
with the E6400 port; a default 96MHz clock is still used for
pixel reference clock, overridden with a value of 100MHz on
other GM45 machines, where 96MHz was previously hardcoded.

The E6400 uses a 100 MHz reference clock on DPLL_REF_SSCLK, whereas
libgfxinit assumed that the reference was always 96 MHz. The frequency
difference caused by a 100 MHz reference with PLL config values
calculated assuming a 96 MHz reference were not significant enough to
cause noticable issues with the more common 1280 x 800 panels, but are
enough to matter for the 1440 x 900 panels which use a higher pixel
clock. This only affected the pre-OS graphics environment provided by
libgfxinit, as Linux drivers would determine the reference clock
frequency based on data in the VBT.
Fix this by making the reference clock frequency in libgfxinit
configurable for GM45 based on a new coreboot Kconfig, which is set to
100 MHz for the E6400.

re-use the same patches, and drop the same patches.
this tree uses hell's special ddr2 fix, which we apply
for the dell latitude e6400.
Signed-off-by: Leah Rowe <leah@libreboot.org>
the ddr2 fix broke *ddr3* on gm45 thinkpads in
testing, depending on memory modules. this was
established by removing patches, re-doing
configs etc, on a user's X200 (testing gentoo
and freebsd). the X200 kept randomly rebooting
or having random glitches.
the configs themselves (gm45 thinkpads) will
also be re-done, because i found minor issues
unrelated, but this patch moves dell e6400 to
its own tree. the ddr2 fix is no longer present
in coreboot/default, only coreboot/dell.
i noticed minor differences in gm45 thinkpad
configs, when re-doing the configs, versus
what are currently in lbmk master; for instance,
vbt was not enabled anymore, on thinkpad x200.
modifications to these will be done separately.

My previous fix to revert didn't fix S3 on GM45, one
of the platforms reported fixed by 78263; I'm merging
that instead, at patch set 10.
It is referenced by 78815/1 which was split from it,
so merge that too (restores overrides of higher values,
on certain platforms that we don't use yet).

Accordingly, update configs to match the new default.

the patch:
https://review.coreboot.org/c/coreboot/+/78270
this has been reverted, because it caused s3 resume
issues on most intel laptops in libreboot.
i was going to merge this instead:
https://review.coreboot.org/c/coreboot/+/78623
however, it's under review, and this doesn't change
to the old behaviour; it keeps the new universal
config, but changes the default
we know the old logic works, so keep that for now.
in fact, the offending patch was only merged to
main in coreboot, one day before i recently
updated coreboot revs in coreboot/default - i used
a 12 october revision, the patch above is 11 october
i then ran "./update trees -u coreboot" which updated
the heap sizes back to the old defaults. this should
fix s3 suspend/resume where it was broken, in the
libreboot 20231021 release - a point release with this
and a few other fixes is planned soon.

Riku's mSATA patch for HP8300USDT was merged upstream, so the
patch has been dropped from lbmk because it is contained within
this new coreboot revision.

build/release/src was partly re-written to accomodate this
memtest86plus was patched to have a central Makefile, and
lbmk modified to use that, rather than mess with build32
and build64. the central Makefile just builds both targets
or cleans both targets
