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

    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.

Subject: [PATCH 11/30] lenovo/x230: set me_state=Disabled in cmos.default
I only recently found out about this. It's possible to use me_cleaner to
do the same thing, but some people might just flash coreboot and not do
anything with the ME region
With this change, the ME is set to disabled. It's my understanding that this
will accomplish more or less the same thing as me_cleaner, without actually
using that. Of course, I still recommend using me_cleaner
I saw this when I audited coreboot's git history, and saw this:
