the current entry is fine, but it would then not support
other configs of different flash sizes, unless they are
explicitly defined.

Iru Cai's port from Gerrit:
https://review.coreboot.org/c/coreboot/+/39398
Now with the proper MXM structure, which removes the 30 second POST
delay. Tested with i7-2670QM, Quadro 2000M and 32GB RAM.

on a dgpu setup, igpu was still in use, when tested
by a user. do separate roms that don't enable anything
vga in coreboot, relying instead only on seabios to
execute a vga rom. these roms will only work if you
have a graphics card.

Specifically the MT versions. The SFF versions will
be added separately, in a later commit.
See: https://review.coreboot.org/c/coreboot/+/55232
This patch has been added, from patchset 31. It still
has some unresolved issues, on that patchset, but
it should boot. See commit message there.
Of note: I've enabled PCI REBAR, though it's unknown
whether it will work (some comments there about it though,
on that gerrit page).
I've also set CBFS size to 8MB, not the full size of
the BIOS region; this is required on the T440p which
uses the same mrc.bin file, to get S3 working.
TSEG stage cache disabled, as on other Haswell boards.
The setup: SeaBIOS-only as first payload, but with GRUB
enabled as secondary payload. The _grubonly setup has
been enabled here. This way, the config will work on
iGPU and dGPU setups without issue.

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.

the e6400_4mb target has libgfxinit and (if seabios) vgarom
initialisation, but has issues on the nvidia model, even when
using nomodeset. with this target, e6400nvidia_4mb, only
the vgarom initialisation is used, libgfxinit is disabled.
on nvidia models, this one should work a little bit better.
specifically: nouveau crashes on this machine, with libreboot
installed, but you can use nomodeset. however, when libgfxinit
is also enabled, nomodeset no longer works properly.
so this target disables all video initialisation in coreboot.
only seabios will initialise anything video-related, by
executing the vga option rom.

Inside the BIOS update, there's 68SCE and 68SCF variants.
Based on Qubes HCL and browsing linux-hardware.org, these are
Probook 6360b and Elitebook 8460p respectively.
I checked the KBC1126 EC Firmwares within the update file, both
use the exact same firmware images. Following-up will be a very
similar but untested port for 6360b.

note: me6_update_parser needs to be written, similar
to me7_update_parser, to generate the partition
tables within intel me6 on lenovo bios updates.
the current logic in lbmk goes like this:
mkdir -p vendorfiles/cache/
and save your factory dump as:
vendorfiles/cache/x201_factory.rom
the build system has been modified, in such a way
as to support extracting me.bin (which is the full
one) and then neutering from this.
this is done automatically, if the file is present,
but you must first insert that file there, which means
you'll need a dump of the original boot flash on your
thinkpad x201

in the future, we may start downloading files that aren't
blobs, such as mxm port configs (on mainboards that use
MXM graphics)
this directory will contain all of those files
generally change the language used, across lbmk, to make
use of "vendorfile" instead of "blob"
