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

1348 Please make sure to pick the right CPU type. Linux/MIPS is not
1349 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1350 *not* work on R4000 machines and vice versa. However, since most
1351 of the supported machines have an R4000 (or similar) CPU, R4x00
1352 might be a safe bet. If the resulting kernel does not work,
1353 try to recompile with R3000.

1576 Loongson 2F03 and later have fixed these issues and no workarounds
1577 are needed. The workarounds have no significant side effect on them
1578 but may decrease the performance of the system so this option should
1579 be disabled unless the kernel is intended to be run on 2F01 or 2F02

1922 a value of 11 means that the largest free memory block is 2^10 pages.

2492 When this is enabled, the kernel will support use of 64-bit floating
2493 point registers with binaries using the O32 ABI along with the
2494 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2495 32-bit MIPS systems this support is at the cost of increasing the
2496 size and complexity of the compiled FPU emulator. Thus if you are
2497 running a MIPS32 system and know that none of your userland binaries
2498 will require 64-bit floating point, you may wish to reduce the size
2499 of your kernel & potentially improve FP emulation performance by
2500 saying N here.

Paul Burton06e2e882014-02-14 17:55:18 +00002502 Although binutils currently supports use of this flag the details
2503 concerning its effect upon the O32 ABI in userland are still being
2504 worked on. In order to avoid userland becoming dependant upon current
2505 behaviour before the details have been finalised, this option should
2506 be considered experimental and only enabled by those working upon
2507 said details.
