Choose this option to build a kernel for release 2 or later of the

MIPS processor are based on a MIPS32 processor. If you know the

Release 2 of the MIPS32 architecture is available since several
years so chances are you even have a MIPS32 Release 2 processor
in which case you should choose CPU_MIPS32_R2 instead for better
performance.
