it didn't work in the past, but it does work nowadays;
specifically, it only worked with libgfxinit in the past,
but not on VGA ROMs.

now it does work on VGA ROMs, tested on e6400 and t1650 so
it was enabled there.

in this setup, a special image is provided where SeaBIOS is
the main payload, but it only loads GRUB; nothing else, every.

this is called SeaGRUB. this setup is useful in cases where
the user only has a GPU that lacks libgfxinit support.

when printing the name of the rom being created, it's
done before the check to rename based on vendorfiles
in target.cfg. this patch fixes that bug.

it wasn't being copied right

the roms under elf/ were being copied, but not the ones
under bin/ - i need to audit it further

for now, i run modify_coreboot_roms from build/roms
instead of update/trees

so, the ones under elf/ no longer have bootblocks copied.
it's only done in bin/

when building only for u-boot, the current script
works just fine. however, when building for other
payloads in additional to u-boot, the final u-boot
stage fails because other payloads are already
inserted via cbfs.

when we build u-boot, we do that last because we want
u-boot setups to only be u-boot, nothing else.

this patch enables qemu x86 to build properly with
u-boot.

keymaps weren't being set in keymay.cfg of cbfs, due
to use of x_ in the rom script, and x_ doesn't handle
quotes or spaces in arguments well.

i'm going to remove use of x_ and xx_ (it's in my todo),
for next release.

for now, hot patch the release. i've gone through and
replaced use of x_ with || err, in some places.

not just the keymap.cfg command, but others too. in case
there are more issues we missed.

this commit is being tagged "20231021fix" and i'm using
this tag to re-build the 20231021 release. i'll just
replace the tarballs in rsync and add errata to the news
page announcing the release. all i did was break peoples
umlauts, i didn't brick their machines fortunately!

very minor bug. anyway, x_/xx_ is a great idea, but sh
isn't really designed for that style of programming. i'll
go back to using just || err in the next release.

as opposed to the current 3-level structure.

recent build system simplifications have enabled
this change, thus:

./build fw coreboot -> ./build roms
./build fw grub -> ./build grub
./build fw serprog -> ./build serprog
./update project release -> ./update release
./update project trees -> ./update trees
./update vendor download -> ./vendor download
./update vendor inject -> ./vendor inject

alper criticised that the commands were too long,
so i made them shorter!

move it all to other files where items are used, and not
used anywhere else. this reduces the size of vendor.sh.

also remove a few redundant variables, or variables that
are not meaningfully used.

a few items have been moved to include/option.sh

The "u-boot.bin" file generated by U-Boot builds is a raw binary. When
adding payloads to a CBFS, we need to use ELF files with add-payload
or manually pass the entry point and load address of the payload binary
with add-flat-binary.

We primarily use the "u-boot.elf" which gets build with the REMAKE_ELF
option, as it also has the necessary device-tree binary that U-Boot
usually needs to work. When the option is not set (e.g. for QEMU), we
need to use the "u-boot" file which is an ELF.
