1434 Please make sure to pick the right CPU type. Linux/MIPS is not
1435 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1436 *not* work on R4000 machines and vice versa. However, since most
1437 of the supported machines have an R4000 (or similar) CPU, R4x00
1438 might be a safe bet. If the resulting kernel does not work,
1439 try to recompile with R3000.

1664 help
1665 Choose this option if you want to enable the Extended Physical
1666 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1667 benefit is to increase physical addressing equal to or greater
1668 than 40 bits. Note that this has the side effect of turning on
1669 64-bit addressing which in turn makes the PTEs 64-bit in size.
1670 If unsure, say 'N' here.

1685 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1686 require workarounds. Without workarounds the system may hang
1687 unexpectedly. For more information please refer to the gas
1688 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1689
1690 Loongson 2F03 and later have fixed these issues and no workarounds
1691 are needed. The workarounds have no significant side effect on them
1692 but may decrease the performance of the system so this option should
1693 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1694 systems.
1695
1696 If unsure, please say Y.

2046 The kernel memory allocator divides physically contiguous memory
2047 blocks into "zones", where each zone is a power of two number of
2048 pages. This option selects the largest power of two that the kernel
2049 keeps in the memory allocator. If you need to allocate very large
2050 blocks of physically contiguous memory, then you may need to
2051 increase this value.
2052
2053 This config option is actually maximum order plus one. For example,
2054 a value of 11 means that the largest free memory block is 2^10 pages.

2652 running a MIPS32 system and know that none of your userland binaries

2707 Find out whether you have a PCI motherboard. PCI is the name of a
2708 bus system, i.e. the way the CPU talks to the other stuff inside
2709 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
2710 say Y, otherwise N.

2744 The Extended Industry Standard Architecture (EISA) bus was
2745 developed as an open alternative to the IBM MicroChannel bus.
2746
2747 The EISA bus provided some of the features of the IBM MicroChannel
2748 bus while maintaining backward compatibility with cards made for
2749 the older ISA bus. The EISA bus saw limited use between 1988 and
2750 1995 when it was made obsolete by the PCI bus.
2751
2752 Say Y here if you are building a kernel for an EISA-based machine.
