Revision Identification Register (RID)
The RID register contains the revision identification
number. This field is initially cleared. Write operations
from the PCI interface have no effect on this register.
After reset is removed, this field can be boot-loaded
from the external non-volatile device (if present and
valid) so that another value may be used.
