The 4KSD is still a MIPS32 processor - just one with an ASE.
The real bug here - and what's causing your confusion - is that the
processor configuration is mixing up all the architecture variants
(MIPS I - IV, MIPS32 and MIPS64 R1/R2, weirdo variants ...) and the
processor types. Example: 4K, 4KE, 24K, 24KE, 34K, AMD Alchemy are all
MIPS32 (either R1 or R2). R4000, R4400, R4600 are all MIPS III. But
what we actually offer in the processor configuration is R4X00, MIPS32_R1,
Ralf
