Same concept as SeaGRUB, but for U-Boot. SeaBIOS starts, but
has a bootorder file loading U-Boot first, from flash.
You can interrupt it with the ESC menu, to boot something else
in SeaBIOS, including GRUB.
With this, we can effectively provide extremely user-friendly
UEFI-first setups in Libreboot.
Take that, edk2!

This is a patch from Simon Glass. U-Boot clears the display
when it starts up, but was asking the VESA driver to do the
same, needlessly; this patch avoids the latter.
A further patch is also included, which provides a better
message when jumping into long mode on the SPL (64-bit) target,
dumping it on the serial console instead of using printf.

For some reason, 32-bit U-Boot only works when executed from
GRUB, but not SeaBIOS; 64-bit U-Boot only works from SeaBIOS!
This will have to be investigated. Standalone U-Boot, where
U-Boot is the primary payload, has not yet been tested in
Libreboot, and will not be provided for some time due to
stability concerns. More testing is needed!

U-Boot was hanging on hardware, but not Qemu. This is because on
the machines tested, namely the X200 and E6230 laptops supported
in Libreboot, the UART was disabled from coreboot.
This U-Boot patch from Simon Glass works around the issue by
silently disabling the UART when it isn't there. Instead,
output is sent to the display and U-Boot no longer hangs.

When building a coreboot image, if they enable the
x86 U-Boot payloads, sometimes what happens is you
have CROSS_COMPILE set, for i386-elf, but then it's
still set to that when later building 64-bit U-Boot,
which needs x86_64-elf.
We currently rely on hostcc to build U-Boot.
To mitigate this, unset CROSS_COMPILE in the main
loop of the trees script, for building project targets.

Currently seems to stall when booted from the GRUB
payload, but works when booted from the SeaBIOS menu.
I also tested it as a standalone payload and it seems

it to more mainboards.

NOTE: Support added for xarch target x86_64-elf,
but U-Boot failed to build with this error:
OBJCOPY lib/efi_loader/helloworld.efi
x86_64-elf-objcopy: lib/efi_loader/helloworld_efi.so: invalid bfd target
make[2]: *** [scripts/Makefile.lib:476: lib/efi_loader/helloworld.efi] Error 1
Since I'm building U-Boot for x86_64 *on* an x86-64
host, and since that is currently the recommended type
of machine to use for lbmk development, and since the
other x86 payloads currently don't cross compile anyway,
this is an acceptable compromise for now. This is because
at present, I'm not making U-Boot the primary payload on x86,
instead preferring to chain it from GRUB and SeaBIOS.
The target.cfg file for x86 u-boot shows xarch/xtree commented.
Uncomment these to compile on crossgcc instead of hostcc.
I mention 64-bit because I initially did this first, but decided
to do 32-bit first. I'll work on the 64-bit one next (SPL).
It's only enabled in QEMU for now.

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.

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 MEC5035 S3 patches to the versions that were sent upstream
to prevent conflicts with subsequent patches for that EC.
- 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
host so that the OS can decide what to do. Without it, the EC powers
off the system without letting the OS cleanly shut down.

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.
