There were a lot of unnecessary patches, such as the VRAM
patches; as Nicholas Chin has explained to me, the drivers
for these machines will just allocate what RAM they want
anyway, so in a lot of cases the extra allocated Video RAM
simply reduces the total amount of memory for other uses.
In general, we have a lot of patches that have existed for
years. A much more aggressive sweep will be done in the next
major audit, especially when the revisions are updated again.

Remove what is now unnecessary bloat, for ensuring that
GRUB is the primary payload; SeaGRUB is the only preference,

Again, I'm adapting the config to be as close to the
coreboot one as possible. I compiled directly from coreboot
earlier, and got SeaBIOS to work on my 3050.
I'm matching the setup as closely as possible. Once it works,
I can use that in a Libreboot release but then debug why the
old config wasn't working.

I'm eliminating as many differences as possible between lbmk's
setup, and the setup that is default when simply building from
the gerrit patch, directly in coreboot, by just picking the
mainboard; in this way, coreboot picks SeaBIOS as payload. I
already changed the SeaBIOS configs, in the previous patch.
Upon testing, this seems to have fixed the SeaBIOS hanging. I
need to have both of these options selected, or SeaBIOS hangs
just after it says "Press ESC" for the boot menu.
With this config change, SeaBIOS does not hang; instead, it shows
the list of devices as normal, and boots your machine.

- Update the patch that enables the S3 SMI handler in mainboard code so
that all Latitudes use the handler.
- Add a new patch that tells the EC to route power button events to the

Specifically, use the same revision that Mate used in patchset 15.
This will ensure that any issues are *not* caused by the coreboot
revision; this is being done, because the old coreboot revision was
from July, but patchset 15 from Mate is based on a September revision
of coreboot.
I've been eliminating as many variables as possible, trying to fix
SeaBIOS payload on this machine, because it hangs in Libreboot, but
not when building from gerrit directly, which means the coreboot
revision may be a factor (since I'm using his patches on an older
revision so upstream might have made some changes since then that
the port relies on).
For this, a new coreboot tree is used, called "dell7", referring to
the fact that Kabylake is Intel's 7th generation.

Use patchset 15 instead of 14:
config/coreboot/default/patches/0061-WIP-OptiPlex-3050-Micro-port.patch
Rebase the verb patch; patchset 15 modified the Makefile:
config/coreboot/default/patches/0064-dell-optiplex_3050-add-hda_verb.c.patch
We were using patchset 14 for the 3050 micro:
https://review.coreboot.org/c/coreboot/+/82053/14
Now we use patchset 15:
https://review.coreboot.org/c/coreboot/+/82053/15
Without this patch, the fans are always on a low setting, on
the Dell OptiPlex 3050 Micro, even under stress conditions. With
this patch, the fans change speed according to CPU temperature.
I had to rebase my verb patch, because Mate modified the Makefile
to add his sch5555 handler, on the same line where I add hda_verb.
Mate tells me he will merge my verb and vbt patches into a further
patchset later on. For now, I've simply rebased these patches on
top of Mate's newer work; I've told him he can use them in his port.
I'm probably going to now issue a new revision ROM image for
Libreboot 20241008, so that users can get this fix sooner.

the .git directory never exists anyway, when doing a release,
so the purpose this is intended is defeated by lbmk's design.
individual headers say "pcsx-redux team" as copyright anyway,
and the code for generating that COPYING file, with MIT license
and correct years (matching the entire source code for the
open bios) remains correct.
a mitigation instead of this patch might be to maintain a hardcoded
list of authors, and manually update it over time, but this is not
required. however, it may be good practise for upstream to maintain
such a file. perhaps i should contact them?

commit d128a0ae87086b37c0e5d7a8d934bcdee173402f

flashchips: Remove unsupported erase blocks for Winbond W25X{16,32,64}
This family of chips does not support the 0x52 (32 KiB block erase) and
0x60 (chip erase) opcodes according to their datasheet.
The full list of changes this brings in is as follows:
* d128a0a flashchips: Remove unsupported erase blocks for Winbond W25X{16,32,64}
* c6a924a Don't mention writing when erasing only (-E)
* dac4239 ch347_spi: Add 'spimode' parameter
* 56d236b chipset_enable: Add some newer AMD code names
* 3b9f152 chipset_enable: Probe AMD SPIBAR first and bail on ff
* 522160f meson: Add ft4222_spi
Nicholas Chin's patch fixes a bug on GM45 ThinkPads, where WX25
ICs (Winbond) could be read, but writes would fail in certain
cases because flashchips.c provided incorrect block erase commands.
This is unrelated to the --workaround-mx patch, for Macronix ICs.

I also checked the copyright declarations in the
directory src/mips/openbios where the PCSX-Redux BIOS
is, gleaning all the copyright years: 2019-2024 at this
time.
The years will be updated as and when PCSX-Redux is
updated in lbmk. Their BIOS is under MIT so I made lbmk
generate an appropriate COPYING file alongside the binary,
containing:
Copyright (c) 2019-2024 PCSX-Redux authors
Along with the actual text of the MIT license. With all
of this, the PCSX-Redux BIOS can now be included in
Libreboot releases.
No actual tarball is created. The release script in lbmk
simply copies the bin/ directory to ../roms
I'm leaving the PCSX-Redux BIOS release uncompressed,
because, and this will sound patronising because that is
my precise intention: Windows users don't know how to do
anything. If I provide a tarball to Windows users, they
won't know what to do. Libreboot releases always go on rsync
mirrors, which also have HTTP servers with indexing enabled,
for browsing release files.
I mention Windows users, because most people who use the PCSX
Redux BIOS will probably use it on a PlayStation emulator, and
most emulator users are on Windows. I can't really be bothered
to provide it as a .zip archive, and it's only 512kb, so just
provide it uncompressed in Libreboot releases!
Releases were already possible under this scheme, so this
patch really just adds the COPYING file. It's simply a courtesy
to the PCSX-Redux developers, providing proper credit to them.

on 3050micro, we disable seabios as a primary payload,
making grub a pribary payload instead.
the way it worked, the roms were still named seagrub
and the seabios rom would be compiled, but with the wrong
path, so seabios wouldn't be executed; seabios would hang
anyway, on this board.
instead, engineer it in such a way as to disable seabios_
images on this board. also, rename seagrub_ to grub_.
i normally only permit seagrub, and not grub, but i make an
exception for 3050micro because we know grub works, but seabios
currently hangs on this board (which means no bsd).

in some cases, on a fresh clone, the cached repo already
exists but lbmk tries to download it again. work around
this by checking that the directory exists; it's in the
main if statement, so that the "else" still applies. as
a result, the fallback to a live repo would un-fall back
to doing git-pull if the cached directory exists exists.
if it doesn't seem to make sense, it's because it doesn't.
this whole function needs to be rewritten better.

This is using Mate Kukri's port, which was added in
previous lbmk revisions. I've added an IFD that sets
the HAP bit, and unlocks regions as standard.
vcfg is set to 3050micro, which defines downloading
of the MEv11 image and it will run deguard automatically.
I made a small adjustment to vendor.sh, because the hotpatch
logic for deguard uses -C in git, and when doing that, the
specified directory path is relative to that Git repository;
the .patch path has been adjusted accordingly.
Also add 3rdparty/fsp to coreboot/default modules.
This board requires the ifdtool option: -p sklkbl
The -p option tells flashrom what quirks are present in a
given IFD. We don't normally need this on other Libreboot
targets that we currently support. The -p option was needed
for creating this modified IFD, and it is therefore needed in
the inject script. Therefore, an "IFD_platform" option is
specified in a given board's target.cfg file. If this is set,
another variable is set that makes -p be used.
In this case, 3050's target.cfg says:
IFD_platform="sklkbl"
This option enables quirks for skylake/kabylake descriptors,
as required when using ifdtool.

Copy the downloaded deguard source code into appdir,

standalone. The archived one in src/ is not directly

This is because the standalone version already has

the output isn't really super critical, because it pertains
to files that would just result in a coreboot build error
if they didn't extract, which would still allow me to know
if a given extract function failed.
however, the extract function shows a lot of error output
because it literally bruteforces various extract methods,
when dealing with vendor files.
mitigate this by just printing the errors to /dev/null. this
will prevent users from erroneously thinking that lbmk is
operating under error condition, when it isn't. we do sometimes
get questions about it on irc.
fewer questions on irc is better.

Commit 3ee4cc9dde (fix typo in dell

$(CONFIG_VARIANT_DIR). While this does work, since CONFIG_VARIANT_DIR is
a valid variable, it is not technically correct, as the default VBT path
set by coreboot's Kconfig files uses $(VARIANT_DIR), which is the same
as CONFIG_VARIANT_DIR, but with quotes stripped out.
