797 This option supports all of the Octeon reference boards from Cavium
798 Networks. It builds a kernel that dynamically determines the Octeon
799 CPU type and supports all known board reference implementations.
800 Some of the supported boards are:
801 EBT3000

1390 Please make sure to pick the right CPU type. Linux/MIPS is not
1391 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1392 *not* work on R4000 machines and vice versa. However, since most
1393 of the supported machines have an R4000 (or similar) CPU, R4x00
1394 might be a safe bet. If the resulting kernel does not work,

1968 The kernel memory allocator divides physically contiguous memory
1969 blocks into "zones", where each zone is a power of two number of
1970 pages. This option selects the largest power of two that the kernel
1971 keeps in the memory allocator. If you need to allocate very large
1972 blocks of physically contiguous memory, then you may need to
1973 increase this value.
1974
1975 This config option is actually maximum order plus one. For example,
1976 a value of 11 means that the largest free memory block is 2^10 pages.

2567 point registers with binaries using the O32 ABI along with the
2568 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2569 32-bit MIPS systems this support is at the cost of increasing the
2570 size and complexity of the compiled FPU emulator. Thus if you are
2571 running a MIPS32 system and know that none of your userland binaries
