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

1389 Please make sure to pick the right CPU type. Linux/MIPS is not
1390 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1391 *not* work on R4000 machines and vice versa. However, since most
1392 of the supported machines have an R4000 (or similar) CPU, R4x00
1393 might be a safe bet. If the resulting kernel does not work,

1967 The kernel memory allocator divides physically contiguous memory
1968 blocks into "zones", where each zone is a power of two number of
1969 pages. This option selects the largest power of two that the kernel
1970 keeps in the memory allocator. If you need to allocate very large
1971 blocks of physically contiguous memory, then you may need to
1972 increase this value.
1973
1974 This config option is actually maximum order plus one. For example,
1975 a value of 11 means that the largest free memory block is 2^10 pages.

2566 point registers with binaries using the O32 ABI along with the
2567 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On

2569 size and complexity of the compiled FPU emulator. Thus if you are
2570 running a MIPS32 system and know that none of your userland binaries
