566 can simulate a MIPS32 4Kc system. This patch adds support for the
567 system architecture that currently is being simulated by Qemu. It
568 will eventually be removed again when Qemu has the capability to
569 simulate actual MIPS hardware platforms. More information on Qemu

1166 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1168 of the supported machines have an R4000 (or similar) CPU, R4x00
1169 might be a safe bet. If the resulting kernel does not work,
