82 want to choose R4xx0 for the CPU Type:

746 This option enables special console drivers which allow the kernel
747 to print messages very early in the bootup process.
748
749 This is useful for kernel debugging when your machine crashes very
750 early before the console code is initialized. For normal operation
751 it is not recommended because it looks on some machines ugly and
752 oesn't cooperate with an X server. You should normally N here,

1020 Please make sure to pick the right CPU type. Linux/MIPS is not
1021 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1022 *not* work on R4000 machines and vice versa. However, since most
1023 of the supported machines have an R4000 (or similar) CPU, R4x00
1024 might be a safe bet. If the resulting kernel does not work,
1025 try to recompile with R3000.

1904 Select this option if you want Linux/MIPS 32-bit binary
1905 compatibility. Since all software available for Linux/MIPS is
1906 currently 32-bit you should say Y here.

1922 Select this option if you want to run o32 binaries. These are pure
1923 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1924 existing binaries are in this format.

1926 If unsure, say Y.

1932 Select this option if you want to run n32 binaries. These are
1933 64-bit binaries using 32-bit quantities for addressing and certain
1934 data that would normally be 64-bit. They are used in special
1935 cases.
