don't handle "romtype" at all, in board target.cfg files
add /dev/null as pike2008 rom on amd boards. this serves
the same purpose, adding them as empty vga roms, to add
an empty rom in cbfs. pike2008 cards cause seabios to hang,
when their oproms are executed, so we insert a fake rom
on i945 thinkpads, use the coreboot config option:
CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK
when set, this enables the same bootblock copy, for use
with bucts. these two cases, namely pike2008 roms and
i945 bootblock copies, no longer need to be handled in code

in cases where lbmk must always return from a function,
there are some cases where it relies on non-zero exit
status, which in practise is always the case, but may
change in the future if the relevant part is modified
e.g. do_something && return 0
the proper form is:
do_something
return 0

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 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.

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.

some users reported build errors. technically, there's

hostcc is hit or miss when it comes to cross compiling

lbmk needs to handle cross compilation. for now, i'm just

Just one script.
Just one!
Well, two, but the 2nd one already existed:
logic in update/project/trees and
update/project/repo was merged into
include/git.sh and update/project/build
was renamed to update/project/trees; an -f
option was added, which calls the functions
under git.sh
so git clones are now handled by the main build
script (for handling makefiles and defconfigs)
but the logic there is a stub, where git.sh
does all the actual heavy lifting
this cuts the file count down by two, and reduces
sloccount a reasonable amount because much of
the logic already exists in the build script, when
it comes to handling targets. git.sh was adjusted
to integrate with this, rather than act standalone

The benefit now is that it can be cleaned. E.g.
./update project build -b coreboot utils
./update project build -b coreboot utils default
./update project build -c coreboot utils
./update project build -c coreboot utils default

are provided after the project name. if the first one
is "utils", then it acts in the same way as the old
build/coreboot/util script

it's buggy. "./build fw coreboot" was made to work,

return with error status if no images were compiled
if a rom image fails to compile, then it will also
exit with error status, but sometimes you can pass
argument "cros" or "default", and it would not give
you rom images due to no target.cfg files, but these
are also ignored because of that.
this restores the same behaviour that existed before,

errors are not defined for mktemp, and the /tmp file

Instead of having detailed error messages, run most
commands through a function that calls err() under
fault conditions.
Where detail is still required, err() is still called
manually. Where it isn't, the error message is simply
whatever command was executed to cause the error.
This results in a massive sloccount reduction for lbmk;
specifically, 178 sloc reduction, or a 8.1% reduction.
The total sloccount is now 2022, for shell scripts.

also: further reduce the number of arguments passed,
to certain functions as and when feasible, in cases
where those are global variables that never change.
the cbfstool argument in mkUbootRom wasn't even used.
that function was only using the global variable, which
again is only set once.
i also shortened a few messages, removed a few errant
line breaks and reduced sloccount by exactly 1 in main()
by re-arranging how the shift command is used.
it's mainly about shortening variable names, to then
reduce the number of line breaks, but it's a surgical
code size reduction in build/boot/roms.

These are only ever initialised globally, and set once.

-k, -p and -d let you set keymap, payload and displaymode

The *same* main() function is now used on both scripts.
However, merging both scripts together would be less efficient

sha-1 has known collision issues, which may not be readily

a more secure method for checking file integrity.
therefore, use sha-2 (sha512sum) for checking files. this is

part of what lbmk does, so the overall effect on build times
