1251 Please make sure to pick the right CPU type. Linux/MIPS is not
1252 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1253 *not* work on R4000 machines and vice versa. However, since most
1254 of the supported machines have an R4000 (or similar) CPU, R4x00
1255 might be a safe bet. If the resulting kernel does not work,
1256 try to recompile with R3000.

1818 this allows for a dual processor. Both processors will share the same
1819 primary caches; each will obtain the half of the TLB for it's own

1838 This is a kernel model which is known a SMTC or lately has been
1839 marketesed into SMVP.
1840 is presenting the available TC's of the core as processors to Linux.
1841 On currently available 34K processors this means a Linux system will
1842 see up to 5 processors. The implementation of the SMTC kernel differs
1843 significantly from VSMP and cannot efficiently coexist in the same
1844 kernel binary so the choice between VSMP and SMTC is a compile time
1845 decision.

2411 Select this option if you want Linux/MIPS 32-bit binary
2412 compatibility. Since all software available for Linux/MIPS is
2413 currently 32-bit you should say Y here.

2429 Select this option if you want to run o32 binaries. These are pure
2430 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
2431 existing binaries are in this format.

2440 64-bit binaries using 32-bit quantities for addressing and certain
