1660 Please make sure to pick the right CPU type. Linux/MIPS is not
1661 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1662 *not* work on R4000 machines and vice versa. However, since most
1663 of the supported machines have an R4000 (or similar) CPU, R4x00
1664 might be a safe bet. If the resulting kernel does not work,
1665 try to recompile with R3000.

1866 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1867 benefit is to increase physical addressing equal to or greater
1868 than 40 bits. Note that this has the side effect of turning on
1869 64-bit addressing which in turn makes the PTEs 64-bit in size.

1885 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1886 require workarounds. Without workarounds the system may hang
1887 unexpectedly. For more information please refer to the gas
1888 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1889
1890 Loongson 2F03 and later have fixed these issues and no workarounds
1891 are needed. The workarounds have no significant side effect on them
1892 but may decrease the performance of the system so this option should
1893 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1894 systems.

3088 Beware that there is very little in terms of protection against
3089 this option being confused by leftover garbage in memory that might
3090 look like a DTB header after a reboot if no actual DTB is appended
3091 to vmlinux.bin. Do not leave this option active in a production kernel
3092 if you don't intend to always append a DTB.
