1338 MIPS64 architecture. Many modern embedded systems with a 64-bit
1339 MIPS processor are based on a MIPS64 processor. If you know the
1340 specific type of processor in your system, choose those that one
1341 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.

1350 Please make sure to pick the right CPU type. Linux/MIPS is not
1351 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1352 *not* work on R4000 machines and vice versa. However, since most
1353 of the supported machines have an R4000 (or similar) CPU, R4x00
1354 might be a safe bet. If the resulting kernel does not work,
1355 try to recompile with R3000.
