1286 Please make sure to pick the right CPU type. Linux/MIPS is not
1287 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1288 *not* work on R4000 machines and vice versa. However, since most
1289 of the supported machines have an R4000 (or similar) CPU, R4x00
1290 might be a safe bet. If the resulting kernel does not work,
1291 try to recompile with R3000.

1509 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1510 require workarounds. Without workarounds the system may hang
1511 unexpectedly. For more information please refer to the gas
1512 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1513
1514 Loongson 2F03 and later have fixed these issues and no workarounds
1515 are needed. The workarounds have no significant side effect on them
1516 but may decrease the performance of the system so this option should
1517 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1518 systems.

1857 a value of 11 means that the largest free memory block is 2^10 pages.

2078 increased security at both hardware and software level for
2079 smartcards. Enabling this option will allow proper use of the
2080 SmartMIPS instructions by Linux applications. However a kernel with

2433 When this is enabled, the kernel will support use of 64-bit floating
2434 point registers with binaries using the O32 ABI along with the
2435 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2436 32-bit MIPS systems this support is at the cost of increasing the
2437 size and complexity of the compiled FPU emulator. Thus if you are
2438 running a MIPS32 system and know that none of your userland binaries
2439 will require 64-bit floating point, you may wish to reduce the size
2440 of your kernel & potentially improve FP emulation performance by
2441 saying N here.
2442
Paul Burton06e2e882014-02-14 17:55:18 +00002443 Although binutils currently supports use of this flag the details
2444 concerning its effect upon the O32 ABI in userland are still being
2445 worked on. In order to avoid userland becoming dependant upon current
2446 behaviour before the details have been finalised, this option should
2447 be considered experimental and only enabled by those working upon
2448 said details.
2449
2450 If unsure, say N.

2522 The Extended Industry Standard Architecture (EISA) bus was
2523 developed as an open alternative to the IBM MicroChannel bus.
2524
2525 The EISA bus provided some of the features of the IBM MicroChannel
2526 bus while maintaining backward compatibility with cards made for
2527 the older ISA bus. The EISA bus saw limited use between 1988 and
2528 1995 when it was made obsolete by the PCI bus.
