20090819-2-trim-down-cbfs:
CBFS uses sprintf, which requires vtxprintf, which requires (in the current design) a nested function. That works on x86, but on PPC this requires a trampoline. In the ROM stage, this is not available, so remove the single use of sprintf and replace it with a direct string handler - it's only used to fill in fixed-length hex values. 20090819-3-more-noreturns-in-romcc: Mark two more functions in romcc as noreturn. Helps clang's scan-build a bit 20090819-4-cbfsify-ppc: Make PPC use CBFS. Support big endian ELF in cbfs-mkstage. Untested and not complete yet. 20090819-5-fix-ppc-build: The CBFS build system requires ROM_IMAGE_SIZE to have a somewhat plausible value. With fixes to tohex* functions as discussed on the list, and correct function names.
