/* Board configuration array.
* This array defines the hardware irq and address for up to IP2_MAX_BOARDS
* (4 supported per ip2_types.h) ISA board addresses and irqs MUST be specified,
* PCI and EISA boards are probed for and automagicly configed
* iff the addresses are set to 1 and 2 respectivily.
* 0x0100 - 0x03f0 == ISA
* 1 == PCI
* 2 == EISA
* 0 == (skip this board)
* This array defines the hardware addresses for them. Special
* addresses are EISA and PCI which go sniffing for boards.
* In a multiboard system the position in the array determines which port
* devices are assigned to each board:
* board 0 is assigned ttyF0.. to ttyF63,
* board 1 is assigned ttyF64 to ttyF127,
* board 2 is assigned ttyF128 to ttyF191,
* board 3 is assigned ttyF192 to ttyF255.
*
* In PCI and EISA bus systems each range is mapped to card in
* monotonically increasing slot number order, ISA position is as specified
* here.
* If the irqs are ALL set to 0,0,0,0 all boards operate in
* polled mode. For interrupt operation ISA boards require that the IRQ be
* specified, while PCI and EISA boards any nonzero entry
* will enable interrupts using the BIOS configured irq for the board.
* An invalid irq entry will default to polled mode for that card and print
* console warning.
* When the driver is loaded as a module these setting can be overridden on the
* modprobe command line or on an option line in /etc/modules.conf.
* If the driver is built-in the configuration must be
* set here for ISA cards and address set to 1 and 2 for PCI and EISA.
*
* Here is an example that shows most if not all possibe combinations:
*static ip2config_t ip2config =
*{
* {11,1,0,0}, // irqs
* { // Addresses
* 0x0308, // Board 0, ttyF0 - ttyF63// ISA card at io=0x308, irq=11
* 0x0001, // Board 1, ttyF64 - ttyF127//PCI card configured by BIOS
* 0x0000, // Board 2, ttyF128 - ttyF191// Slot skipped
* 0x0002 // Board 3, ttyF192 - ttyF255//EISA card configured by BIOS
* // but polled not irq driven
* }
*};
*/
/* this structure is zeroed out because the suggested method is to configure
* the driver as a module, set up the parameters with an options line in
* /etc/modules.conf and load with modprobe, kerneld or kmod, the kernel
* module loader
*/
/* This structure is NOW always initialized when the driver is initialized.
* Compiled in defaults MUST be added to the io and irq arrays in
* ip2.c. Those values are configurable from insmod parameters in the
* case of modules or from command line parameters (ip2=io,irq) when
* compiled in.

{
{0,0,0,0}, // irqs
