859 This option supports all of the Octeon reference boards from Cavium
860 Networks. It builds a kernel that dynamically determines the Octeon
861 CPU type and supports all known board reference implementations.
862 Some of the supported boards are:
863 EBT3000
864 EBH3000
865 EBH3100
866 Thunder
867 Kodama
868 Hikari

1451 Please make sure to pick the right CPU type. Linux/MIPS is not
1452 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1453 *not* work on R4000 machines and vice versa. However, since most
1454 of the supported machines have an R4000 (or similar) CPU, R4x00
1455 might be a safe bet. If the resulting kernel does not work,
1456 try to recompile with R3000.

2673 When this is enabled, the kernel will support use of 64-bit floating
2674 point registers with binaries using the O32 ABI along with the
2675 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2676 32-bit MIPS systems this support is at the cost of increasing the
2677 size and complexity of the compiled FPU emulator. Thus if you are
2678 running a MIPS32 system and know that none of your userland binaries
2679 will require 64-bit floating point, you may wish to reduce the size
2680 of your kernel & potentially improve FP emulation performance by
2681 saying N here.

2683 Although binutils currently supports use of this flag the details
2684 concerning its effect upon the O32 ABI in userland are still being
2685 worked on. In order to avoid userland becoming dependant upon current
2686 behaviour before the details have been finalised, this option should
2687 be considered experimental and only enabled by those working upon
2688 said details.
2689
2690 If unsure, say N.

2815 The Extended Industry Standard Architecture (EISA) bus was
2816 developed as an open alternative to the IBM MicroChannel bus.

2818 The EISA bus provided some of the features of the IBM MicroChannel
2819 bus while maintaining backward compatibility with cards made for
2820 the older ISA bus. The EISA bus saw limited use between 1988 and
2821 1995 when it was made obsolete by the PCI bus.
