1268 Some MIPS machines can be configured for either little or big endian
5e83d430 1269 byte order. These modes require different kernels and a different
3cb2fccc 1270 Linux distribution. In general there is one preferred byteorder for a
5e83d430 1271 particular system but some systems are just as commonly used in the
3dde6ad8 1272 one or the other endianness.

1896 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.

1898 Loongson 2F03 and later have fixed these issues and no workarounds
1899 are needed. The workarounds have no significant side effect on them
1900 but may decrease the performance of the system so this option should
1901 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1902 systems.

3069 Beware that there is very little in terms of protection against
3070 this option being confused by leftover garbage in memory that might
3071 look like a DTB header after a reboot if no actual DTB is appended
3072 to vmlinux.bin. Do not leave this option active in a production kernel
3073 if you don't intend to always append a DTB.
