1558 Choose this option to build a kernel for release 2 or later of the
1559 MIPS64 architecture. Many modern embedded systems with a 64-bit
1560 MIPS processor are based on a MIPS64 processor. If you know the
1561 specific type of processor in your system, choose those that one
1562 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.

1576 Choose this option to build a kernel for release 6 or later of the
1577 MIPS64 architecture. New MIPS processors, starting with the Warrior
1578 family, are based on a MIPS64r6 processor. If you own an older

1590 Please make sure to pick the right CPU type. Linux/MIPS is not
1591 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1592 *not* work on R4000 machines and vice versa. However, since most
1593 of the supported machines have an R4000 (or similar) CPU, R4x00
1594 might be a safe bet. If the resulting kernel does not work,
1595 try to recompile with R3000.

1808 help
1809 Choose this option if you want to enable the Extended Physical
1810 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1811 benefit is to increase physical addressing equal to or greater
1812 than 40 bits. Note that this has the side effect of turning on
1813 64-bit addressing which in turn makes the PTEs 64-bit in size.
1814 If unsure, say 'N' here.

1829 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1830 require workarounds. Without workarounds the system may hang
1831 unexpectedly. For more information please refer to the gas
1832 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1833
1834 Loongson 2F03 and later have fixed these issues and no workarounds
1835 are needed. The workarounds have no significant side effect on them
1836 but may decrease the performance of the system so this option should
1837 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1838 systems.
1839
1840 If unsure, please say Y.

2949 point registers with binaries using the O32 ABI along with the
2950 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2951 32-bit MIPS systems this support is at the cost of increasing the
2952 size and complexity of the compiled FPU emulator. Thus if you are
2953 running a MIPS32 system and know that none of your userland binaries
2954 will require 64-bit floating point, you may wish to reduce the size
2955 of your kernel & potentially improve FP emulation performance by
