1341 Release 2 of the MIPS64 architecture is available since several
1342 years so chances are you even have a MIPS64 Release 2 processor
1343 in which case you should choose CPU_MIPS64_R2 instead for better
1344 performance.

1356 Choose this option to build a kernel for release 2 or later of the
1357 MIPS64 architecture. Many modern embedded systems with a 64-bit
1358 MIPS processor are based on a MIPS64 processor. If you know the
1359 specific type of processor in your system, choose those that one
1360 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.

1384 Please make sure to pick the right CPU type. Linux/MIPS is not
1385 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1386 *not* work on R4000 machines and vice versa. However, since most
1387 of the supported machines have an R4000 (or similar) CPU, R4x00
1388 might be a safe bet. If the resulting kernel does not work,
1389 try to recompile with R3000.
