1028 Please make sure to pick the right CPU type. Linux/MIPS is not
1029 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1030 *not* work on R4000 machines and vice versa. However, since most
1031 of the supported machines have an R4000 (or similar) CPU, R4x00
1032 might be a safe bet. If the resulting kernel does not work,
1033 try to recompile with R3000.

1977 Select this option if you want Linux/MIPS 32-bit binary
1978 compatibility. Since all software available for Linux/MIPS is
1979 currently 32-bit you should say Y here.

1994 help
1995 Select this option if you want to run o32 binaries. These are pure
1996 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1997 existing binaries are in this format.

1999 If unsure, say Y.

2005 Select this option if you want to run n32 binaries. These are
2006 64-bit binaries using 32-bit quantities for addressing and certain
2007 data that would normally be 64-bit. They are used in special
2008 cases.
