[coreboot] [commit] r6511 - trunk/util/kconfig

[repository service]

Author: stepan
Date: Mon Apr 18 04:07:16 2011
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.
