New Revision: 712
URL: http://tracker.coreboot.org/trac/openbios/changeset/712
Log:
Move the Forth loader forthload.c from arch/*/forthload.c to libopenbios/forth_load.c. While the Forth loader source was
included and built as part of the SPARC64 and SPARC32 builds, it was never actually invoked in the boot sequence. Hence this
patch maintains the existing behaviour in that only X86 builds included the Forth loader.
