Riku introduced three new patches:
* Add support for multiple chip selects. This allows you to
control multiple chips from the same clip, on systems with
dual flash setups, at least theoretically.
* Enable pull-up on unused chip selects - pull them high so
that chips you connect that to are deactivated while flashing
the target chip. This could be used on thinkpad W541 for
instance, where miso/mosi have 0ohm between them via the two
flash ICs. You could pull the other chip select high.
* Documentation for the above, in the pico-serprog readme.
This goes in tandem with a patch from Riku, present in the
recently integrated flashprog project, namely:

This functionality will therefore be present in the next
release of Libreboot.

Nico Huber is the rightful project lead. I do not support
the coup that occured within the flashrom project. Nico
has always been of great service to the Libreboot project,
by virtue of his work on both coreboot and flashrom.
Nico Huber was unfairly removed from the flashrom project
infrastructure, due to unfounded accusations hurled at him
by flashrom's new project lead. The accusations are unfounded
because no evidence was given.
Use Nico Huber's fork, named flashprog. We will work with
flashprog from now on.

in some cases, the build system was needlessly, and sometimes
erroneously, creating crossgcc symlinks, which then caused an
issue, namely:
in lbmk release builds, dell e6400 is build before fam15h boards,
and it sets xtree, but fam15h_rdimm doesn't, and later this would
cause fam15h_rdimm boards to use xtree="default" (because they don't
set xtree), causing the newer toolchain to be used on coreboot 4.11.
this patch fixes the issue. quite a simple problem, actually.

CONFIG_PS2M_EISAID. this is a a string used for the
identifier on the mouse, in ACPI.
CONFIG_PS2K_EISAID this is used for the keyboard.
IASL comes back with this build error:
dsdt.asl 1884: Name(_HID, EISAID("DLLK0534"))
Error 6045 - ^ EISAID string must be of the form "UUUXXXX" (3 uppercase, 4 hex digits) (DLLK0534)
Change DLLK0534 back to PNP0303 and
change DLL0534 back to PNP0F13. These are generic identifiers
for PS/2 keyboard and mouse. Any generic driver will work with
the onboard mouse/keyboard on these machines. They do not need
to be changed. These are the default values anyway. Just leave
them explicitly defined to the default values, for now; if these
options are not set, coreboot will default to these values.
This shouldn't break anything for the users. I've reported this
to Nicholas Chin, author of those patches. Libreboot imported
the new versions of E6430/E6530 board patches in the coreboot
revision update, but the new (technically correct) values broke
IASL, so I've decided to use the old values for now.

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/+/80023https://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).

the boarddir variable is only set *after* detect_board
is run, and is in fact checked after that. this check,
removed by this patch, is too early and causes lbmk
to exit with error states. this patch fixes the error.
the error was that lbmk was then searching for a file
that is at an empty path.

and neither does lbmk. i changed a few of them when doing
the crossgcc build optimisation patches.

There is no need to add multiple keymap files, because
GRUB can load keymaps from CBFS. The current build logic
is designed to avoid building multiple GRUB binaries,
which are expensive computationally because each one
would then have to be compressed for each board.
This patch provides the best of both worlds: less space
used in flash like in the old lbmk design (1 keymap per
board), but retaining the current build speeds and therefore
not re-introducing the slowness of lbmk's previous GRUB
build logic.
The grub.cfg file has been modified, accordingly. It now
only loads a keymap.gkb file from CBFS, by default. It does
this, only if that file exists; if not, GRUB already defaults
to US Qwerty layout anyway.
ALSO: compress all keymap gkb files with xz -6
GRUB automatically decompresses files when accessed.
This results in about 2KB of flash space saved in CBFS.
Here is real-world data, showing the increased flash space:
< fallback/payload 0x3eb80 simple elf 548821 none
< keymap.cfg 0xc4bc0 raw 16 none
< (empty) 0xc4c00 null 11633316 none
---
> fallback/payload 0x3eb80 simple elf 546787 none
> keymap.gkb 0xc43c0 raw 344 none
> (empty) 0xc4540 null 11635044 none
This was taken by diffing the cbfstool "print" output,
both before and after. The *after* result is with this change.
11633316. In this example, 1728 bytes have been saved. Therefore,
with compression taken into account, this patch saves about 1.7KB
of space in CBFS.
This change means that lbmk can now scale to support hundreds
of keymaps, without increasing the amount of flash space used,
in each given image. Since the keymap files are compressed in
lbmk.git, in advance, we spend no additional time on compression
at build time. The resulting change in build speed in negligible.
Adding your own keymap.gkb file was already possible, for changing
the keymap in libreboot images, if you didn't want to change the
memdisk (and thus re-compile grub.elf). Now, this is the default
behaviour, and the only way to do it. It's much more efficient.
The original keymap files can be restored, by running unxz.

the "kmapdir" variable was removed in an earlier audit,
but was overlooked for -k because that option was untested.
rather than initialise the variable, re-use grubcfgsdir.
this fix enables e.g. "-k usdvorak" to work again.

with neutered ME, fan control fails. while there are
ways to mitigate it, many users will not, and will
likely see their system overheat, which is very
dangerous.
this bug (failed fan control on neutered ME) only
affects arrandale machines such as lenovo x201.
the newer machines are not affected by this.
other arrandale machines will probably not be added
to libreboot because of this, or they will be subject
to further testing.

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.

In order for the EC to maintain the state of whether or not to set the
flash descriptor override across a power cycle, the AC adapter must be
connected, as the system leaves the voltage rail that the EC uses
powered under this condition. Without this, the utility may fail,
continually asking the user to power off and on.
On Linux, CONFIG_X86_IOPL_IOPERM must be set for the kernel, or else the
iopl call will error with "Function not implemented". Make a note of
this in case a user runs into this issue.
