Author: oxygene Date: Thu Apr 8 13:37:43 2010 New Revision: 5373 URL: https://tracker.coreboot.org/trac/coreboot/changeset/5373
Log: Replace sconfig with a C implementation. (smaller, faster, standard parser generator, no more python)
Provide precompiled parser, so bison and flex are optional dependencies.
Adapt Makefile and abuild (which uses some sconfig file as a magic path) to match.
Drop python as dependency from README, and add bison and flex as optional dependencies
