Keep in mind that the PCMCIA + * spec specifies the CIS as the lower 8 bits of each word read from + * the CIS, so to read the bytes of the CIS, read every other byte + * (0,2,4,...). Passing that test, you need to enable the I/O address + * space on the PCMCIA card via the PCMCIA COR register. This is the + * first byte following the CIS. In my case (which may not have any + * relation to what's on the PRISM2 cards), COR was at offset 0x800 + * within the PCI memory space. Write 0x41 to the COR register to + * enable I/O mode and to select level triggered interrupts. To + * confirm you actually succeeded, read the COR register back and make + * sure it actually got set to 0x41, in case you have an unexpected + * card inserted. + * + * Following that, you can treat the second PCI I/O address space (the + * one that's not 0x80 in length) as the PCMCIA I/O space. + * + * Note that in the Eumitcom's source for their drivers, they register + * the interrupt as edge triggered when registering it with the + * Windows kernel. I don't recall how to register edge triggered on + * Linux (if it can be done at all). But in some experimentation, I + * don't see much operational difference between using either + * interrupt mode. Don't mess with the interrupt mode in the COR + * register though, as the PLX9052 wants level triggers with the way + * the serial EEPROM configures it on the WL11000. + * + * There's some other little quirks related to timing that I bumped + * into, but I don't recall right now. Also, there's two variants of + * the WL11000 I've seen, revision A1 and T2. These seem to differ + * slightly in the timings configured in the wait-state generator in + * the PLX9052. There have also been some comments from Eumitcom that + * cards shouldn't be hot swapped, apparently due to risk of cooking + * the PLX9052. I'm unsure why they believe this, as I can't see + * anything in the design that would really cause a problem, except + * for crashing drivers not written to expect it. And having developed + * drivers for the WL11000, I'd say it's quite tricky to write code + * that will successfully deal with a hot unplug. Very odd things + * happen on the I/O side of things. But anyway, be warned.
