the update/trees script checks this binary itself, before
deciding whether to recompile/compile, so we don't need
to do such checks here.

the script can now also handle autoconf build systems,
whereas this could previously only be done for grub.
with this change, the overall sloccount is also lower

arch no longer needs to be set, on multi-tree projects,
and it has been renamed to xarch
the new behaviour is: if xarch is set, treat it as a
list of crossgcc targets and go through the list. set
the first one as the target, for what lbmk builds, but
build all of the defined crossgccc targets
crossgcc_ada is now xlang, and defines which languages
to build, rather than whether to build gcc-gnat

while seemingly pedantic, this does actually make code
easier to read. mostly just switching to shorthand for

which is then used, but these are called inside what
are essentially subshells, and we had no error handling

cros roms are always using libgfxinit, with a coreboot

lbmk used to set version/versiondate directly in
err.sh, but now it's handled there by a function,
which is called by the main script.
script/update/release hadn't yet been adapted. the
only change necessary is to call check_project()
script/update/trees also makes use of it
script/build/roms is using "projectname"

at present, lbmk can remove microcode updates on images for
a given target, if the target specifies
microcode_required="n" in target.cfg
lbmk then provides images with microcode, and images without,
in a given release. although the user can also remove them
manually, this just makes it a bit more convenient, for those
users who do wish to run without the updates. this functionality
is provided only on those platforms where no-microcode is tested.
well, this behaviour implements a compromise on libreboot policy,
which is to always include microcode updates by default. see:
Binary Blob Reduction Policy
the *canoeboot* project now exists, developed in parallel with
libreboot, and it ships without microcode updates, on the same
targets where lbmk also handled this.
running without microcode updates is foolish, and should not
be encouraged. clean up lbmk by not providing this kludge.
the libreboot documentation will be updated, telling such users
to try canoeboot instead, or to remove the update from a given
libreboot rom - this is still possible, and mitigations such as
PECI disablement on GM45 are still in place (and will be kept),
so that this continues to work well.

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

all it did was set -v in the shell, which doesn't yield
very useful results. this is a relic of very old design

most of these are probably redundant, and will never
be called, but lbmk needs to be as safe as possible
under fault conditions. fail early, fail hard.

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
also do this for unconditional exits

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.

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.

some users reported build errors. technically, there's
nothing wrong with lbmk but it relies on hostcc, and
hostcc is hit or miss when it comes to cross compiling
32-bit, depending on the build system of whatever project.
lbmk needs to handle cross compilation. for now, i'm just
disabling memtest86plus on non-64-bit hosts.

the script used to be called once per target, now it
handles every target. the grub background image wasn't
being set, so if it changed at build time, it would
stay changed.
keep the default in place for each run, while still
allowing target.cfg files to change it per target.

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
the update/project/build script checks when arguments
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
