952 This option supports all of the Octeon reference boards from Cavium
953 Networks. It builds a kernel that dynamically determines the Octeon
954 CPU type and supports all known board reference implementations.
955 Some of the supported boards are:
956 EBT3000
957 EBH3000
958 EBH3100
959 Thunder
960 Kodama
961 Hikari
962 Say Y here for most Octeon reference boards.

1645 Please make sure to pick the right CPU type. Linux/MIPS is not
1646 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1647 *not* work on R4000 machines and vice versa. However, since most
1648 of the supported machines have an R4000 (or similar) CPU, R4x00
1649 might be a safe bet. If the resulting kernel does not work,
1650 try to recompile with R3000.

1851 Choose this option if you want to enable the Extended Physical
1852 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1853 benefit is to increase physical addressing equal to or greater
1854 than 40 bits. Note that this has the side effect of turning on
1855 64-bit addressing which in turn makes the PTEs 64-bit in size.

1871 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1872 require workarounds. Without workarounds the system may hang
1873 unexpectedly. For more information please refer to the gas
1874 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1875
1876 Loongson 2F03 and later have fixed these issues and no workarounds
1877 are needed. The workarounds have no significant side effect on them
1878 but may decrease the performance of the system so this option should
1879 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1880 systems.

3092 Beware that there is very little in terms of protection against
3093 this option being confused by leftover garbage in memory that might
3094 look like a DTB header after a reboot if no actual DTB is appended
3095 to vmlinux.bin. Do not leave this option active in a production kernel
3096 if you don't intend to always append a DTB.
