resources/coreboot/default/patches: Add patch for E6400 SD card
This fixes the PCI interrupt routing tables for the E6400 so that the SD
card works. It is already merged in upstream but libreboot has not yet
updated coreboot.

Remove warning for coreboot images build without a payload
I added this in upstream to prevent people from accidentally flashing
roms without a payload resulting in a no boot situation, but in
libreboot lbmk handles the payload and thus this warning always comes
up. This has caused confusion and concern so just patch it out.

Leah Rowe 3da0ee4f73 remove python3 patches
python 3 is default now, in all the distros

specifically calling "python3" often doesn't work anymore

python2 is obsolete

let python2 die

Leah Rowe bd4ea9a028 gm45: re-add mitigations for no-microcode setup
libreboot will still include microcode updates
by default, but mitigations against broken speedstep
and reboot (when microcode updates are excluded) were
removed following the merge with osboot

this patch restores those mitigations; the patch
reverts coreboot to older smrr code (which works fine, it
isn't critical to use the new behaviour) and disables peci
(pointless feature)

i'll probably re-tool this later to apply the changes
conditionally to whether ucode is present

this is not a change in policy. policy says:
include cpu microcode updates by default

policy also says:
libreboot must be configurable

microcode removal via cbfstool remove -n, counts as
configuration, and in practise is not possible on
gm45 patches in current libreboot; this patch corrects
that problem, allowing the machines to work somewhat
well (same stability issues as before, like MCE errors
resulting in kernel panic on high CPU/memory usage,
but i digress)

happy... hacking

Leah Rowe a5aa5bca77 ICH9M: default to 256MB VRAM, not 352MB
352MB VRAM causes stability issues, according to some reports

users can still set it to the higher level when building, if
they wish to

Leah Rowe 7679c8e0f0 coreboot/default: add --nuke flag to ifdtool

Alexei Sorokin a33e842908 coreboot: add x230edp_12mb, remove x230fhd_12mb
New x230edp_12mb target uses the
https://review.coreboot.org/c/coreboot/+/28950 patchset to add an
X230_EDP target to the default coreboot branch.
Consequently the "fhd" coreboot branch is no longer needed and has
been safely removed.

Leah Rowe 7af9953463 pragmatic system distribution guideline compliance
osboot is now part of libreboot, and will soon shut down.
libreboot now conforms to osboot policy.

Leah Rowe 8ca0761fb0 specifically call python3, in scripts
with this change, it's unlikely we'll hit errors again. previously,
some projects used were calling "python" which in context was
python3, but on some setups, the user only has python2 and python3
but no symlink for "python" (which if exists, we assumed linked to
python3)

now it's unambiguous. docs/build/ can probably be updated now, as
a result of this change, to remove the advice about that

Leah Rowe 9938fa14b1 Fix broken SpeedStep on GM45 laptops such as ThinkPad X200, T400, T500, W500
Coreboot is enabling PECI on these CPUs which, according to Intel erratum, must
only be done after loading microcode updates, otherwise the CPUID feature set
becomes corrupted. That's my understanding, and I think this is why SpeedStep
is broken. To be specific, it could but but operating systems no longer detect
that the feature is supported. In any case, belgin on IRC found the commit in
coreboot, after a bisect, enabling PECI. This commit in Libreboot adds a patch,
reverting coreboot's PECI patch.

Leah Rowe eed25bd220 update coreboot and nuke tianocore
tianocore is a liability for the libreboot project. it's a bloated mess, and
unreliable, broken on many boards, and basically impossible to audit.

i don't trust tianocore, so i'm removing it.

Leah Rowe c2720c58e7 lenovo/t400: Enable all SATA ports (add persmule's patch)
See:
<https://lists.nongnu.org/archive/html/libreboot/2016-08/msg00063.html>

This enables all SATA ports, allowing full T400s compatibility. T400s already
works just fine, when flashing a T400 ROM, but not all SATA ports were usable.

The specific patch is here:
<https://lists.nongnu.org/archive/html/libreboot/2016-08/txtgT_L8DC94R.txt>

There was also this patch, which coreboot actually adapted upstream:
<https://lists.nongnu.org/archive/html/libreboot/2016-08/txtMXyws85Q_P.txt>

Yes, this patch was submitted in 2016. I overlooked it, during all this time.

Leah Rowe 62fa042a17 re-add grub backgrounds and update grub. mitigate missing characters
mitigate missing characters in unifont for border/arrow characters. this saves
space because now it is no longer necessary to add a custom font

the background added has the libreboot logo on it, and it's 10kb in size unlike
the old gnulove background that was hundreds of KB

This fixes issue 3:

In this issue, GM45 laptops such as X200/T400 will hang on reboot (normal boot
works, and shutting down works too).

Leah Rowe 89517ed6b9 libreboot!
this is forked from the "libre" branch in osboot, which is itself a libre,
deblobbed fork of osboot, a blobbed up fork of libreboot

libreboot needed to be purged clean. this is the new libreboot development
repository. the old one has been abandoned
