Vendor Identification Register

Two of the fields in the Vendor Identification register are not defined for
the RavenMPIC implementation, but are defined in the MPIC
specification. They are the vendor identification and device ID fields.

STP

Stepping. The stepping or silicon revision number is
initially 0.

Processor Init Register

P1

Processor 1. Writing a 1 to P1 will assert the Soft Reset
input of processor 1. Writing a 0 to it will negate the
SRESET signal.

P0

Processor 0. Writing a 1 to P0 will assert the Soft Reset
input of processor 0. Writing a 0 to it will negate the
SRESET signal.
