New Revision: 6511
URL: https://tracker.coreboot.org/trac/coreboot/changeset/6511
Log:
Emit unwritten symbols in Kconfig so we don't have to do constructs like
#if defined(CONFIG_FOO) && CONFIG_FOO anymore. This was partially implemented
but didn't work for symbols that were unset because of a missing dependency.
Patch taken from SeaBIOS.
