here is a quick question ..?

what should be appropiate compilation flag for MIPS RC32134/Rc32334..?
currently i am trying in arch/mips/Makefile
 GCCFLAGS        += -mcpu=r4600 -mips2 -Wa,--trap

But I doubt it for two reasons.

1.I think mips1 should be used instead of mips2 because
if you follow mips literature mips 2* and 3* series fall under MIPS1 category.
4* and bigger series comes under MIP2 and MIPS3 series.

for example CONFIG_CPU_LLSC is not enabled for all MIPS1
category processors.

2.Is -mcpu=r4600 switch is alright for Rc32334?
I was just wondering why i should use -mcpu=r4600 for RC323334
