/*
* This is a PCI shim for the Wavelan wireless network driver.
* It works with PCI adaptors based on the PLX 9050 and PLX 9052
* PCI to "dumb bus" bridge chip. It has been tested with the
* Global Sun Technology GL24110P02 (aka Linksys WDT11), 3Com 3CRWE777A,
* and Netgear MA301. It is also expected to work with the
* Global Sun GL24110P and Eumitcom WL11000P.
*
* All we do here is handle the PCI match and attach, set up an
* interrupt handler entry point, and setup the PLX chip for level
* interrupts and config index 1.
*
* The PLX 9052 provides us with multiple PCI address space mappings.
* The primary mappings at PCI registers 0x10 (mem) and 0x14 (I/O) are for
* the PLX chip itself, *NOT* the pcmcia card.
* The PLX 9052 provides 4 local address space registers: 0x18, 0x1C,
* 0x20, and 0x24. The mem and I/O spaces for the PCMCIA card are
* mapped to 0x18 and 0x1C respectively.
*
* The datasheet may be downloaded from PLX (though you do have to register)
* http://www.plxtech.com/products/toolbox/9050.htm
