791 This option supports all of the Octeon reference boards from Cavium
792 Networks. It builds a kernel that dynamically determines the Octeon
793 CPU type and supports all known board reference implementations.
794 Some of the supported boards are:
795 EBT3000
796 EBH3000
797 EBH3100
798 Thunder
799 Kodama
800 Hikari
801 Say Y here for most Octeon reference boards.

1346 Please make sure to pick the right CPU type. Linux/MIPS is not
1347 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1348 *not* work on R4000 machines and vice versa. However, since most
1349 of the supported machines have an R4000 (or similar) CPU, R4x00
1350 might be a safe bet. If the resulting kernel does not work,
1351 try to recompile with R3000.

1574 Loongson 2F03 and later have fixed these issues and no workarounds
1575 are needed. The workarounds have no significant side effect on them
1576 but may decrease the performance of the system so this option should

1920 a value of 11 means that the largest free memory block is 2^10 pages.

2433 kexec is a system call that implements the ability to shutdown your

2490 When this is enabled, the kernel will support use of 64-bit floating
2491 point registers with binaries using the O32 ABI along with the
2492 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2493 32-bit MIPS systems this support is at the cost of increasing the
2494 size and complexity of the compiled FPU emulator. Thus if you are
2495 running a MIPS32 system and know that none of your userland binaries
2496 will require 64-bit floating point, you may wish to reduce the size
2497 of your kernel & potentially improve FP emulation performance by
2498 saying N here.

2502 worked on. In order to avoid userland becoming dependant upon current

2504 be considered experimental and only enabled by those working upon
2505 said details.
