--- Comment #4 from Tobias Platen <libre-soc at platen-software.de> ---
In src/soc/simple/core.py I added this line:          
self.decoders["mmu0"].mmu0_spr_dec = self.decoders["spr0"] 
after having found out using GTKWave that the insn_type for mmu0 is OP_INVALID
in my unit test where is use "mtspr 18, 1". The correct insn_type for DSISR DAR
SVSRR0 and PIDR is passed to the wrong function unit instead.
