334 6869 d 15 h jermar /SPARTAN/trunk/arch/ Cleanup.

332 6869 d 15 h palkovsky /SPARTAN/trunk/ Updated symtab so that it works correctly with BE architectures.

330 6870 d 10 h palkovsky /SPARTAN/trunk/arch/mips/ Fixed bad address loading in simulators.

Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.
