This is taken from cpu/mips/config.mk

MIPSFLAGS=$(shell \
if [ "$v" -lt "14" ]; then \
        echo "-mcpu=4kc -EB -mabicalls"; \
else \
        echo "-march=4kc -mtune=4kc -Wa,-mips_allow_branch_to_undefined -EB -mabicalls"; \
fi)

Also, this is part from Makefile:

ifeq ($(ARCH),mips)
CROSS_COMPILE = mips_4KC-
endif

So, what is all this then, an exercise in obfuscation? I can tell, it 
was successfully, I really thought only 4kc is supported, my apologies, 
Wolfgang.

Anyway, my comment still stands, this is bogus and cannot work for 4kc 
at least. The only reason INCA-IP port works is because memory is 
really initialized before stack is accessed.
