1285 Please make sure to pick the right CPU type. Linux/MIPS is not
1286 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1287 *not* work on R4000 machines and vice versa. However, since most
1288 of the supported machines have an R4000 (or similar) CPU, R4x00
1289 might be a safe bet. If the resulting kernel does not work,
1290 try to recompile with R3000.

1508 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1509 require workarounds. Without workarounds the system may hang
1510 unexpectedly. For more information please refer to the gas
1511 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1512
1513 Loongson 2F03 and later have fixed these issues and no workarounds
1514 are needed. The workarounds have no significant side effect on them
1515 but may decrease the performance of the system so this option should
1516 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1517 systems.

1856 a value of 11 means that the largest free memory block is 2^10 pages.

2077 increased security at both hardware and software level for
2078 smartcards. Enabling this option will allow proper use of the
2079 SmartMIPS instructions by Linux applications. However a kernel with

2432 When this is enabled, the kernel will support use of 64-bit floating
2433 point registers with binaries using the O32 ABI along with the
2434 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2435 32-bit MIPS systems this support is at the cost of increasing the
2436 size and complexity of the compiled FPU emulator. Thus if you are
2437 running a MIPS32 system and know that none of your userland binaries
2438 will require 64-bit floating point, you may wish to reduce the size
2439 of your kernel & potentially improve FP emulation performance by
2440 saying N here.
2441
Paul Burton06e2e882014-02-14 17:55:18 +00002442 Although binutils currently supports use of this flag the details
2443 concerning its effect upon the O32 ABI in userland are still being
2444 worked on. In order to avoid userland becoming dependant upon current
2445 behaviour before the details have been finalised, this option should
2446 be considered experimental and only enabled by those working upon
2447 said details.
2448
2449 If unsure, say N.

2521 The Extended Industry Standard Architecture (EISA) bus was
2522 developed as an open alternative to the IBM MicroChannel bus.
2523
2524 The EISA bus provided some of the features of the IBM MicroChannel
2525 bus while maintaining backward compatibility with cards made for
2526 the older ISA bus. The EISA bus saw limited use between 1988 and
2527 1995 when it was made obsolete by the PCI bus.
