1230 Please make sure to pick the right CPU type. Linux/MIPS is not
1231 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1232 *not* work on R4000 machines and vice versa. However, since most
1233 of the supported machines have an R4000 (or similar) CPU, R4x00
1234 might be a safe bet. If the resulting kernel does not work,
1235 try to recompile with R3000.

1437 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1438 require workarounds. Without workarounds the system may hang
1439 unexpectedly. For more information please refer to the gas
1440 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1441
1442 Loongson 2F03 and later have fixed these issues and no workarounds
1443 are needed. The workarounds have no significant side effect on them
1444 but may decrease the performance of the system so this option should
1445 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1446 systems.
1447
1448 If unsure, please say Y.

2114 a system with only one CPU, like most personal computers, say N. If
2115 you have a system with more than one CPU, say Y.
2116
2117 If you say N here, the kernel will run on single and multiprocessor
2118 machines, but will use only one CPU of a multiprocessor machine. If
2119 you say Y here, the kernel will run on many, but not all,
