Leah Rowe 4a6dc5553f coreboot/default: update coreboot to January 2024
Base revision changed to:

    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:

    drivers/pc80/rtc/option.c: Stop resetting CMOS during s3 resume

Further patches from upstream:

    drivers/pc80/rtc/option.c: Reset only CMOS range covered by checksum

This should fix S3 on GM45 thinkpads.

Leah Rowe 401c0882aa NEW MAINBOARD: HP EliteBook 820 G2
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.
