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

1068 of the supported machines have an R4000 (or similar) CPU, R4x00
1069 might be a safe bet. If the resulting kernel does not work,
