16650 UART base address. The address should be on a 8 byte boundary. For
reference, 550 compatible UART legacy base addresses are 3E8h, 338h, 2E8h,
220h, 238h, 2E0h, 228h, 3F8h, and 2F8h.

SUBVEN_ID
RO
Subsystem Vendor ID. The Subsystem Vendor ID register allows the
manufacturer to uniquely identify their board since more than one board OEM
may use the SAA7780 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 interface. If no external
EEPROM is present, then the default Subsystem Vendor ID is 1004h, that of
Philips Semiconductors (VLSI Technology).
