1561 Please make sure to pick the right CPU type. Linux/MIPS is not
1562 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1563 *not* work on R4000 machines and vice versa. However, since most
1564 of the supported machines have an R4000 (or similar) CPU, R4x00
1565 might be a safe bet. If the resulting kernel does not work,
1566 try to recompile with R3000.

2482 increased security at both hardware and software level for
2483 smartcards. Enabling this option will allow proper use of the

2952 When this is enabled, the kernel will support use of 64-bit floating
2953 point registers with binaries using the O32 ABI along with the
2954 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2955 32-bit MIPS systems this support is at the cost of increasing the
2956 size and complexity of the compiled FPU emulator. Thus if you are
2957 running a MIPS32 system and know that none of your userland binaries
2958 will require 64-bit floating point, you may wish to reduce the size
2959 of your kernel & potentially improve FP emulation performance by
2960 saying N here.
