it mainly does general tasks, like handling utils
and enabling ccache. the vfiles are a small part.

rename the function accordingly. it is called by
premake, so let's call it corebootpremake.

this change will also make sense when cherry-picked
into cbmk, which does not handle vfiles at all.

define it with a single variable, rather than several.

this allows several checks to be greatly simplified.

remove it from mkhelper files, because rom.sh doesn't
initialise any variables globally, except one that
never changes.

Many users report bugs, so I'm reverting lbmk back to only
supporting the rp2040 dongles for the time being. The
documentation will be updated to reflect this.

Pico2 support will be re-added at a later date, once more
testing has been done, and fixes made if necessary.

this is a file containing one byte, of value zero

i meant to add it in previous commits, for the resizing
and shrinking of tarballs when inserting or deleting
vendor files

used by include/vendor.sh

This is currently the latest revision of coreboot.

Other coreboot trees to follow. The "next" tree will
also be merged with coreboot/default, in a follow-up
commit.

code equals bugs. code that doesn't exist can't
have bugs, so it is superior by definition.

instead of running pwd all the time, run it once in lib.sh,
and export PWD.

for lbmk-specific use of PWD, use xbmkpwd, which contains
the value of PWD as was set by the pwd utility in lib.sh.

many parts of lbmk rely on pwd, and it *must* be correct.
this change adds basic error handling, since pwd can in
fact return errors in some cases.
