move the coreboot-specific includes into mkhelper.cfg
for that project.
on some projects, we need variables from mkhelper.cfg
to be global, so I was including serprog and coreboot
mkhelper.cfg files in this script.
instead, set a new variable "mkhelpercfg" pointing to
the config file. if it doesn't exist, create and then
point to a temporary (empty) mkhelper.cfg file.
the rom.sh include has been moved to coreboot mkhelper.cfg
The only remaining project-specific logic, in this trees
script, is now the coreboot crossgcc handling, but this
needs to be there as it's also used to build U-Boot.
The way this now works, certain includes are done twice.
For example, include/rom.sh will be included once globally,
outside of main(), and then again in configure_project().
This means that certain functions will be defined twice.
I'm uncertain if shell has anything equivalent to an ifdef
guard as in C, but we actually want this here anyway, and
it shouldn't cause any problems. It's a bit of a hack, but
otherwise results in much cleaner code.

-d does the same as -b, except for actually building
anything! in effect, it does the same as -f (fetch)
except that the resulting variable assignments will
not be recursive (as with -f).
if -d is passed, configuration is still loaded, defconfig
files are still cycled through, and more importantly:
helper functions are still processed.
the grub, serprog and coreboot helper functions have
been modified to return early (zero status) if -d is
passed.
this behaviour will be used to integrate vendor.sh
logic in with the trees script, for cases where the
user wants to only handle vendor files. e.g.:
./update trees -b coreboot x230_12mb
this would download the files as usual, build coreboot,
with those files, and then build the payloads. but:
./update trees -d coreboot x230_12mb
this would download the files, NOT build coreboot, and
NOT build the payloads.
this change increases the sloccount a bit, but i'm relying
on the fact that the vendor.sh script already re-implements
config handling wastefully; the plan is to only use trees.
for now, simply stub the same ./vendor download command.
there is one additional benefit to doing it this way:
this method is *per-kconfig* rather than per-target.
this way, one kconfig might specify a given vendor file
that is not specified in the other. although the stub
still simply handles this per target, it's done in premake,
which means that the given .config file has been copied.
this means that when i properly re-integrate the logic
into script/trees, i'll be able to go for it per-kconfig.
the utils command has been removed, e.g.
./update trees -b coreboot utils default
the equivalent is now:
./update trees -d coreboot default
this would technically download vendor files, but here
we are specifying a target for which no kconfigs exist;
a check is also in place, to avoid running the vendor file
download logic if tree==target
the overall effect of this change is that the trees script
no longer contains any project-specific logic, except for
the crossgcc build logic.
it does include some config/data mkhelper files at the top,
for serprog and coreboot, so that those variables defined in
those files can be global, but another solution to mitigate
that will also be implemented in a future commit.
the purpose of this and other revisions (in the final push
to complete lbmk audit 6 / cbmk audit 2) is to generalise as
much logic as possible, removing various ugly hacks.

stub it from the trees script. the way it works now,
there is less code in the build system.
./build roms
this is no longer a thing
./build roms serprog
this is also no longer a thing. instead, do:
./update trees -b coreboot targetnamehere
./update trees -b pico-serprog
./update trees -b stm32-vserprog
the old commands still works, which causes the new
commands to run
coreboot roms now appear in elf/, not bin/, as before,
but those images now contain payloads.
NOTE: to contradict the above: ./build roms is no
longer a thing, in that it's now deprecated, but
backward compatibility is present for now. it will
be removed in a future release.
./build roms list also still works! it will do:
./update trees -b coreboot list
also:
./update trees -b grub list
this is now possible too
if a target "list" is provided, for multi-tree sources,
the targets are shown.
there is another difference: seagrub roms are now seagrub_,
instead of seabios_withgrub.
seabios-only roms are no longer provided, where grub is also
enabled; only seagrub is used. the user can easily remove
the bootorder file, if they want seabios to not try grub first.

stick the makeargs in mkhelper
i previously did cbmakeargs because the old revisions
had to define makeargs per-target otherwise. mkhelper
was done specifically to solve that problem.
