The 33xx0 family are MIPS-compatible designs that were done
in-house at LSI logic.  At the level of the user-mode instruction
set, they are compatible with MIPS-I/R3000 - indeed, the basic
pipeline looks like it was taken directly from the R3000.  But the
system coprocessor was radically modified and simplified and in
particular there is no TLB/MMU.  Standard Linux therefore won't fly
on it, though some variant of uClinux might.
