Hi Ed, 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? Thanks!
