151 want to choose R4xx0 for the CPU Type:

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