Re: [PATCH v2] Add MIPS64R2 core support.

Not exactly - it adds 64R2 support in Malta, plus small verification that build kernel could run 32bit binaries.

I don't think it has sense to multiply patches here, there is no sense to have this separated.

5KEc is just test-bed.

    Looks like the subject is incorrect. Should be "Add MIPS 5KE support"?

    The above looks like a material for separate patch...
