1178 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1179 *not* work on R4000 machines and vice versa. However, since most
1180 of the supported machines have an R4000 (or similar) CPU, R4x00
1181 might be a safe bet. If the resulting kernel does not work,
1182 try to recompile with R3000.
1191 The options selects support for the NEC VR41xx series of processors.
