Fixes this bug:
https://codeberg.org/libreboot/lbmk/issues/216
Well, fix is the wrong word. We want xHCI ideally.
Mate is working on it as I write this. I've also:
* Disabled CONFIG_FINALIZE_USB_ROUTE_XHCI on Haswell
boards (coreboot)
* Disabled the GRUB payload on HP 820 G2 for now
We will need to re-add the xHCI patches once fixed.
If Mate/we can't fix it, I'll contact Patrick
Rudolph who originally wrote the xHCI patches.

See:
https://codeberg.org/libreboot/lbmk/issues/216
Almost all users will be OK running GRUB, but a
minority of users have experienced a fatal error
pertaining to grub_free() or grub_realloc() (as
my investigation of GRUB sources reveal when grepping
the error reported in the link above).
We don't yet know what the bug is, only that the
error occurs, leading to an effective brick if the
user has GRUB as their primary payload.
So far, it has only been reported on some Intel
SandyBridge-based Dell Latitudes in Libreboot, but
we can't be too sure.
The user reported that memtest86+ passes just fine,
and SeaBIOS works; BIOS GRUB also works, which means
that the bug is likely only in an area of GRUB that
runs specifically on the coreboot payload, so it's
probably a driver in GRUB when running on the metal
rather than BIOS/UEFI.
The build system supports a configuration whereby
SeaBIOS is the primary payload, but GRUB is available
in the SeaBIOS boot select menu, and an additional
configuration is available where GRUB is what SeaBIOS
executes first (while still providing boot select);
both of these are now the *only* configurations
available, on all x86 targets except QEMU.
The QEMU target is fine because if the bug occurs there,
you can just close QEMU and try a different image.
Even after this bug is later identified and fixed,
the GRUB source code is vastly over-engineered and there
are likely many more such bugs. SeaBIOS is a reliable
payload; the code is small and robust. Remember always:
Code
equals
bugs
Therefore, this configuration change is likely going
to be permanent. This will apply in the next release.

the release variable is all we need, turning a target on
or off for a given release.
the status checks were prone to bugs, and unnecessary; it
also broke certain benchmark scripts.
it's better to keep the lbmk logic simpler. board status
will be moved to the documentation instead.

export LBMK_VERSION_TYPE=x
x can be: stable, unstable
in target.cfg files, specify:
status=x
x can be: stable, unstable, broken, untested
if unset, lbmk defaults to "unknown"
if LBMK_VERSION_TYPE is set, no confirmation is asked
if the given target matches what's set (but what's set
in that environmental variable can only be stable or
unstable)
if LBMK_RELEASE="y", no confirmation is asked, unless
the target is something other than stable/unstable
"unstable" means it works, but has a few non-breaking
bugs, e.g. broken s3 on dell e6400
whereas, if raminit regularly fails or it is so absolutely
unreliable as to be unusable, then the board should be
declared "broken"
untested means: it has not been tested
With this change, it should now be easier to track whether
a given board is tested, in preparation for releases. When
working on trees/boards, status can be set for targets.
Also: in the board directory, you can add a "warn.txt" file
which will display a message. For example, if a board has a
particular quirk to watch out for, write that there. The message
will be printed during the build process, to stdout.
If status is anything *other* than stable, or it is unstable
but LBMK_VERSION_TYPE is not set to "unstable", and not building
a release, a confirmation is passed.
If the board is not specified as stable or unstable, during
a release build, the build is skipped and the ROM is not
provided in that release; this is in *addition* to
release="n" or release="y" that can be set in target.cfg,
which will skip the release build for that target if "n"

at present, the inject scripts compress refcode in a way
that is not reproducible, so there's no way to verify
that the firmware is correct, via checksum verification,
when injecting vendor code on release images
the lack of reproducibility in recompression will have to be
addressed, but the issue is that lbmk does not provide its own
sources for compression utilities, instead opting to use the
system's own compression utility
so the solution might be for lbmk not to use the host's utility,
and compile its own, or insert the refcode uncompressed. for now,
simply disable the hp 820 g2 target in libreboot releases
this uses the same logic recently implemented for excluding
mrc-based haswell images in libreboot releases

Base revision changed to:
commit b6cbfa977f63d57d5d6b9e9f7c1cef30162f575a
Author: Morris Hsu <morris-hsu@quanta.corp-partner.google.com>
Date: Fri Jan 5 16:48:17 2024 +0800
mb/google/dedede/var/metaknight:Add fw_config probe for multi codec
and amplifier
Of note:
Several out-of-tree ports have been adjusted to use the new SPD config
style, where it is defined in devicetree. I manually updated the E6530
patch myself, based on the update that Nicholas did on E6430 (Nicholas
will later update the E6530 patch himself, and I'll re-merge the patch).
Several upstream patches now exist in this revision, that we were able
to remove from lbmk.
The heap size patch was reverted upstream, as we did, but see:
https://review.coreboot.org/c/coreboot/+/80023
https://review.coreboot.org/c/coreboot/+/79525
Although we still disable the TSEG Stage Cache, ivy/sandy/haswell should
be reliable on S3 now (leaving TSEG Stage Cache disabled, for now, anyway).
Also included in upstream now:
commit 29030d0f3dad2ec6b86000dfe2c8e951ae80bf94
Author: Bill Xie <persmule@hardenedlinux.org>
Date: Sat Oct 7 01:32:51 2023 +0800
drivers/pc80/rtc/option.c: Stop resetting CMOS during s3 resume
Further patches from upstream:
commit 432e92688eca0e85cbaebca3232f65936b305a98
Author: Bill Xie <persmule@hardenedlinux.org>
Date: Fri Nov 3 12:34:01 2023 +0800
drivers/pc80/rtc/option.c: Reset only CMOS range covered by checksum
This should fix S3 on GM45 thinkpads.

This is of Broadwell platform, one generation above Haswell.
Of note: this uses HP Sure Start. Although the flash is 16MB,
our CBFS section (and IFD configuration) assumes 12MB flash,
so the final 4MB will be left unflashed on installation,
after blanking the private flash. The coreboot documents have
more information about this.
Some minor design changes in lbmk were made, to accomodate
this port:
Support for extracting refcode binaries added (pulled from
Google recovery images). The refcode file is an ELF that
initialises the MRC and the PCH. It is also responsible for
enabling or disabling the Intel GbE device, where Google
does not enable it, but lbmk modifies it per the instructions
on the coreboot documentation, so as to enable Intel GbE.
Google's recovery image stores the refcode as a stage file,
but coreboot changed the format (for CBFS files) after 4.13
so coreboot 4.13's cbfstool is used to extract refcode. This
realisation made me also change the script logic to use a
cbfstool and ifdtool version matching the coreboot tree, for
all parts of lbmk, whereas lbmk previously used only the
default tree for cbfstool/ifdtool, on insertion and deletion
of vendor files - it was 81dc20e744 that broke extraction of
refcode on google's recovery images, where google used an older
version of cbfstool to insert the files in their coreboot ROMs.
A further backported patch has been added, copying coreboot
revision f22f408956 which is a build fix from Nico Huber.
Iru Cai submitted an ACPI bugfix after the revision lbmk
currently uses, for coreboot/default, and this fix is
needed for rebooting to work on Linux 6.1 or higher. This
patch has been backported to lbmk, while it still uses the
same October 2023 revision of coreboot.
Broadwell MRC is inserted at the same offset as Haswell,
so I didn't need to tweak that.
