Move option table (cmos.layout's binary representation)
to CBFS and adapt coreboot to use it. Comments by Stefan and Mathias taken into account (except for the build time failure if the table is missing when it should exist and the "memory leak" in build_opt_tbl) Signed-off-by: Patrick Georgi <patrick.georgi@secunet.com> Acked-by: Stefan Reinauer <stepan@coreboot.org> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6268 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
