What kinds of patching did you have to do in the source code except for the
MIPS endian-registers? I've made such changes plus little-endian-fied the
build scripts/linker scripts/makefile/etc. but haven't yet had u-boot working.
I'm assuming that outside of the bootstrapping, the code is endian-independant.
Am I wrong?
