1432 Please make sure to pick the right CPU type. Linux/MIPS is not
1433 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1434 *not* work on R4000 machines and vice versa. However, since most
1435 of the supported machines have an R4000 (or similar) CPU, R4x00
1436 might be a safe bet. If the resulting kernel does not work,
1437 try to recompile with R3000.

1638 Choose this option if you want to enable the Enhanced Virtual
1639 Addressing (EVA) on your MIPS32 core (such as proAptiv).
1640 One of its primary benefits is an increase in the maximum size
1641 of lowmem (up to 3GB). If unsure, say 'N' here.

1663 Choose this option if you want to enable the Extended Physical
1664 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1665 benefit is to increase physical addressing equal to or greater
1666 than 40 bits. Note that this has the side effect of turning on
1667 64-bit addressing which in turn makes the PTEs 64-bit in size.
1668 If unsure, say 'N' here.

1683 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1684 require workarounds. Without workarounds the system may hang
1685 unexpectedly. For more information please refer to the gas
1686 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1687
1688 Loongson 2F03 and later have fixed these issues and no workarounds
1689 are needed. The workarounds have no significant side effect on them
1690 but may decrease the performance of the system so this option should
1691 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1692 systems.
1693
1694 If unsure, please say Y.

2648 32-bit MIPS systems this support is at the cost of increasing the
2649 size and complexity of the compiled FPU emulator. Thus if you are
2650 running a MIPS32 system and know that none of your userland binaries
2651 will require 64-bit floating point, you may wish to reduce the size
2652 of your kernel & potentially improve FP emulation performance by
2653 saying N here.

Paul Burton06e2e882014-02-14 17:55:18 +00002655 Although binutils currently supports use of this flag the details
2656 concerning its effect upon the O32 ABI in userland are still being
2657 worked on. In order to avoid userland becoming dependant upon current
2658 behaviour before the details have been finalised, this option should
2659 be considered experimental and only enabled by those working upon
2660 said details.

2745 The EISA bus provided some of the features of the IBM MicroChannel
2746 bus while maintaining backward compatibility with cards made for
2747 the older ISA bus. The EISA bus saw limited use between 1988 and
