11/* Assigned Company values for bits 23:16 of the PRId Register
70342287 12 (CP0 register 15, select 0). As of the MIPS32 and MIPS64 specs from

13 MTI, the PRId register is defined in this (backwards compatible)

21 I don't have docs for all the previous processors, but my impression is
22 that bits 16-23 have been 0 for all MIPS processors before the MIPS32/64
23 spec.
