542 Qemu is a software emulator which among other architectures also
543 can simulate a MIPS32 4Kc system. This patch adds support for the
544 system architecture that currently is being simulated by Qemu. It
545 will eventually be removed again when Qemu has the capability to
546 simulate actual MIPS hardware platforms. More information on Qemu
547 can be found at http://www.linux-mips.org/wiki/Qemu.

1132 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1134 of the supported machines have an R4000 (or similar) CPU, R4x00
1135 might be a safe bet. If the resulting kernel does not work,
