151 want to choose R4xx0 for the CPU Type:

526 Qemu is a software emulator which among other architectures also
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

1129 Please make sure to pick the right CPU type. Linux/MIPS is not
1130 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1131 *not* work on R4000 machines and vice versa. However, since most
1132 of the supported machines have an R4000 (or similar) CPU, R4x00
1133 might be a safe bet. If the resulting kernel does not work,
1134 try to recompile with R3000.
