1431 Please make sure to pick the right CPU type. Linux/MIPS is not
1432 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1433 *not* work on R4000 machines and vice versa. However, since most
1434 of the supported machines have an R4000 (or similar) CPU, R4x00
1435 might be a safe bet. If the resulting kernel does not work,
1436 try to recompile with R3000.

1637 Choose this option if you want to enable the Enhanced Virtual
1638 Addressing (EVA) on your MIPS32 core (such as proAptiv).
1639 One of its primary benefits is an increase in the maximum size
1640 of lowmem (up to 3GB). If unsure, say 'N' here.

1662 Choose this option if you want to enable the Extended Physical
1663 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1664 benefit is to increase physical addressing equal to or greater
1665 than 40 bits. Note that this has the side effect of turning on
1666 64-bit addressing which in turn makes the PTEs 64-bit in size.
1667 If unsure, say 'N' here.

1682 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1683 require workarounds. Without workarounds the system may hang
1684 unexpectedly. For more information please refer to the gas
1685 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1686
1687 Loongson 2F03 and later have fixed these issues and no workarounds
1688 are needed. The workarounds have no significant side effect on them
1689 but may decrease the performance of the system so this option should
1690 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1691 systems.
1692
1693 If unsure, please say Y.

2655 concerning its effect upon the O32 ABI in userland are still being
2656 worked on. In order to avoid userland becoming dependant upon current
2657 behaviour before the details have been finalised, this option should

2741 The Extended Industry Standard Architecture (EISA) bus was
2742 developed as an open alternative to the IBM MicroChannel bus.
2743
2744 The EISA bus provided some of the features of the IBM MicroChannel
2745 bus while maintaining backward compatibility with cards made for
2746 the older ISA bus. The EISA bus saw limited use between 1988 and
2747 1995 when it was made obsolete by the PCI bus.
