# default is the boardname for the coreboot environment
# used to build tianocore. a "dummy" coreboot ROM is
# build, using the coreboot build system to build tianocore
# and coreboot's build system is modified to not automatically download
# tianocore, and coreboot's Tianocore makefile has some hardcoded stuf:wf

# however, default configs aren't used. a dummy config is in
# resources/tianocore/dummy.coreboot.config for building a coreboot ROM
# with tianocore

# This ROM is discarded, but then tianocore is in place, and fully built.
# Coreboot ROMs in osboot's build system specify "no payload" and
# osboot's build system inserts payloads manually, using cbfstool

# To build the Tianocore payload, run: ./build payload tianocore
