 * SIIG serial cards have an PCI interface chip which also controls

 * are stored in the EEPROM chip. It can cause problems because this
 * version of serial driver doesn't support differently clocked UART's
 * on single PCI card. To prevent this, initialization functions set
 * high frequency clocking for all UART's on given card. It is safe (I
 * hope) because it doesn't touch EEPROM settings to prevent conflicts
 * with other OSes (like M$ DOS).
 *
 *  SIIG support added by Andrey Panin <pazke@donpac.ru>, 10/1999
 *
 * There is two family of SIIG serial cards with different PCI
 * interface chip and different configuration methods:
 *     - 10x cards have control registers in IO and/or memory space;
 *     - 20x cards have control registers in standard PCI configuration space.
 *
 * Note: all 10x cards have PCI device ids 0x10..
 *       all 20x cards have PCI device ids 0x20..
 *
 * There are also Quartet Serial cards which use Oxford Semiconductor
 * 16954 quad UART PCI chip clocked by 18.432 MHz quartz.
 *
 * Note: some SIIG cards are probed by the parport_serial object.

 * This is the configuration table for all of the PCI serial boards
 * which we support.  It is directly indexed by the pci_board_num_t enum
 * value, which is encoded in the pci_device_id PCI probe table's
 * driver_data member.
 *
 * The makeup of these names are:
 *  pbn_bn{_bt}_n_baud{_offsetinhex}
 *
 *  bn		= PCI BAR number
 *  bt		= Index using PCI BARs
 *  n		= number of serial ports
 *  baud	= baud rate
 *  offsetinhex	= offset for each sequential port (in hex)
 *
 * This table is sorted by (in order): bn, bt, baud, offsetindex, n.
 *
 * Please note: in theory if n = 1, _bt infix should make no difference.
 * ie, pbn_b0_1_115200 is the same as pbn_b0_bt_1_115200
