BASE
RW 16650 UART base address. The address should be on a 8 byte boundary. For ref-
erence, 550 compatible UART legacy base addresses are 3E8h, 338h, 2E8h,
220h, 238h, 2E0h, 228h, 3F8h, and 2F8h.
2:1 R RO Reserved. These bits are reserved and always return zeros for plug and play.
0 IO RO I/O flag. This read only bit indicates that this is an I/O range.

15:0 SUBVEN_ID RO Subsystem Vendor ID. The Subsystem Vendor ID register allows the manu-
facturer to uniquely identify their board since more than one board OEM may
use the SSA7785 ThunderBird Avenger™ chip. The Subsystem Vendor ID
register is loaded by an external EEPROM via the Serial Configuration Port
after reset and before any access to the PCI configuration header. The PCI
target logic should force a retry if the Subsystem Vendor ID register has not
completed loading. The Subsystem Vendor ID is read only to the PCI inter-
face. If no external EEPROM is present, then the default Subsystem Vendor
ID is 1004h, that of Philips Semiconductors (VLSI).
