This change adds PPC support to libpayload, and hooks it up in the build
process. The PPC support is still stubbed, with commented out x86 code as guide line for an implementor. Signed-off-by: Patrick Georgi <patrick.georgi@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4293 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
