in this setup, seabios is never the default payload, grub is,
but only if grub is enabled.
set this in target.cfg:
payload_grubsea="y"
if payload_grub isn't enabled, this is auto-set to n
ditto if initmode=normal
NOTE: if flashing libgfx setups, you should make sure
that you're not booting with a graphics card, only intel
graphics. this setting will intentionally not be documented,
because it's not recommended, but is being implemented for
testing purposes (and i implemented it for some guy who i
think is cool). i'll probably also use this myself, since
i already do grub-only setups on all my own machines.
seagrub is the default on x86 because of past instabilities
with grub. to mitigate in case of future issues, since seabios
is always stable, we reduce the chance of bricks.

it's green there. different colour scheme apparently.
still works on x86. alper said his kevin chromebook was green!
was green on the libreboot one, which should be purple.

The bootflow menu is already the default boot command on x86. Switch
arm64 boards to that as well, so instead of booting the first thing we
find, we can easily choose what to boot.

Otherwise, you have to press enter to boot your distro.
With this, a timeout is created. After a number of seconds,
which can be reconfigured, the first option selected will be booted,
when generating a bootflow menu.
The timeout is disabled when you navigate the menu; it only
kicks in if you don't input anything on the keyboard.
More information about how this works is in the U-Boot patches,
within this patch. I've set the timeout to 8 seconds.

Otherwise, you have to press enter to boot, which is unacceptable
for headless operation.
Pressing anything other than enter an an option, such as the arrow
keys, will disable the timeout.

We need to initialize the USB subsystem before we can use USB devices
like keyboards and external disks, by running `usb start`. Use the
PREBOOT config option to run the necessary command before U-Boot tries
to automatically boot anything. It's already enabled for boards other
than gru_kevin and gru_bob, so just update those two configs.

Set default U-Boot revision to v2024.10 and rebase patches on top of
that. The video subsystem now has switched to using the 'cyclic'
mechanism, so the code around one of the video patches changed a bit.
x86 boards were already switched to v2024.10. Update U-Boot for the
remaining ARM64 boards as usual:
- Turn old configs into defconfigs (./update trees -s u-boot)
- Save the diff from old upstream defconfig (diffconfig $theirs $ours)
- Update U-Boot revision, rebase patches, and clean old trees
- Prepare new U-Boot tree (./update trees -f u-boot)
- Review the diffconfigs to see if any options were renamed upstream
- Copy over the new upstream defconfigs and apply earlier diff
- Turn new defconfigs into configs (./update trees -l u-boot)

It wasn't being included, because we remove these files
in Canoeboot's version of U-Boot.
However, rules for including them was still in the U-Boot
build logic, leading to build issues such as:
arch/x86/dts/.cherryhill.dtb.pre.tmp:206:10: fatal error: microcode/m01406c2220.dtsi: No such file or directory
206 | #include "microcode/m01406c2220.dtsi"
This happened when building x86 U-Boot payloads. This patch

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 Canoeboot.
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.
Signed-off-by: Leah Rowe <leah@libreboot.org>
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!

The previous stability issues were resolved, thanks to
the previous revision which added a fix courtesy Simon Glass.
This reverts commit eba73c778a85d1c6ad2f0de57c82a8775cdd1c17.
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.

Currently seems to stall when booted from the GRUB

This version simply updates the revision, whereas
the corresponding lbmk patch was more invasive:

Bump coreboot/next and merge coreboot/dell7
Canoeboot must be in sync with Libreboot at all times.
Well, the Libreboot patch also merges another tree
that Canoeboot doesn't have, containing the Dell OptiPlex
3050 Micro port, because Canoeboot can't support the
OptiPlek 3050 Micro.
So the Libreboot patch rebased many patches. This one
simply updates the revision.

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 cbmk 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.

This is based on the same change recently made in
lbmk. A lot of unnecessary patches, and I want to
clean them all up.
Also, cbmk's /default didn't actually build, whereas
lbmk did, which is the primary motive for this rebase.
With this change, it should build again.

- Update the patch that enables the S3 SMI handler in mainboard code so
that all Latitudes use the handler.

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.
