 * Note that registers are defined here as virtual port numbers,
 * which have no meaning except to get translated by hd64465_isa_port2addr()
 * to an address in the range 0xb0000000-0xb3ffffff.  Note that
 * this translation happens to consist of adding the lower 16 bits
 * of the virtual port number to 0xb0000000.  Note also that the manual
 * shows addresses as absolute physical addresses starting at 0x10000000,
 * so e.g. the NIRR register is listed as 0x15000 here, 0x10005000 in the
 * manual, and accessed using address 0xb0005000 - Greg.
