to ExCA register sets. These registers exist in both ISA and PCI devices in a couple different ways, and this will provide a common base for future building. This code is a rehash of the pccbb 16-bit code, which was a rehash of the pcic code, which was a rehash of the netbsd i82365 code. More hashing to come.
