1554 Choose this option to build a kernel for release 2 or later of the
1555 MIPS64 architecture. Many modern embedded systems with a 64-bit
1556 MIPS processor are based on a MIPS64 processor. If you know the
1557 specific type of processor in your system, choose those that one
1558 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.

1572 Choose this option to build a kernel for release 6 or later of the
1573 MIPS64 architecture. New MIPS processors, starting with the Warrior
1574 family, are based on a MIPS64r6 processor. If you own an older

1586 Please make sure to pick the right CPU type. Linux/MIPS is not
1587 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1588 *not* work on R4000 machines and vice versa. However, since most
1589 of the supported machines have an R4000 (or similar) CPU, R4x00
1590 might be a safe bet. If the resulting kernel does not work,
1591 try to recompile with R3000.

1805 Choose this option if you want to enable the Extended Physical
1806 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1807 benefit is to increase physical addressing equal to or greater
1808 than 40 bits. Note that this has the side effect of turning on
1809 64-bit addressing which in turn makes the PTEs 64-bit in size.

1825 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1826 require workarounds. Without workarounds the system may hang
1827 unexpectedly. For more information please refer to the gas
1828 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1829
1830 Loongson 2F03 and later have fixed these issues and no workarounds
1831 are needed. The workarounds have no significant side effect on them
1832 but may decrease the performance of the system so this option should
1833 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1834 systems.
1835
1836 If unsure, please say Y.

2939 When this is enabled, the kernel will support use of 64-bit floating
2940 point registers with binaries using the O32 ABI along with the
2941 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2942 32-bit MIPS systems this support is at the cost of increasing the
2943 size and complexity of the compiled FPU emulator. Thus if you are
2944 running a MIPS32 system and know that none of your userland binaries
2945 will require 64-bit floating point, you may wish to reduce the size
2946 of your kernel & potentially improve FP emulation performance by
