[openrisc] l.mtspr instruction



Another question ;)
The description of the l.mtspr instruction does not match with the 32-bit implementation:
Description:

The contents of general-purpose register rB are moved into the special register identified by the bit-wise logical OR of general-purpose register rA and the immediate value.

32-bit Implementation:

spr(rB OR Immediate) < - rA[31:0]

 

Could you tell me what is the correct reference?
