This would be useful for architectures which have large numbers of
configuration registers. These are not always mapped in the main address
space. They could conveniently be represented in a separate address
space. Examples include the OpenCores OpenRISC 1000 special purpose
registers and the ARC 600/700 auxiliary address space.
