Appologies for making this one bulk commit, but I have tested all these changes together and don't want to break anything by trying to disentangle it. o Make debugging a sysctl/tunable o Remove flags word from yenta chip info, it is unused o Make 16-bit card I/O range and 32-bit card I/O range tunables o Start the rename of pccbb to cbb to match NetBSD by misc renames. o Kill the now bogus list of softcs to create kthread. Instead, just create the kthread in the attach routine. o Remove sc_ from some structure names. It isn't needed. o Refine chipset lookup code. o Match generic PCI <-> CardBus bridges. We specifically don't generically match PCI PCMCIA bridges because they are not, with one exception, yenta devices. o Add some comments about the why we need to have a function table ala OLDCARD o The PCI interrupt routing by using the ExCA registers is needed for for all bridges, per the spec, not just TI ones. o Collapse TOPIC95 and TOPIC95B. o Using the ToPIC 97 and 100 datasheets, try to support these bridges better, but more work is needed. o Generally clarify some XXX comments and add them in a few places where things didn't look right to me. o Move interrupt generating register access until after we establish an ISR. o Add support for YV and XV cards. X and Y are numbers to be determined later (but maybe never). o factor powerup code for 16-bit and 32-bit cards. o When a card supports more than one voltage, prefer the lowest supported volage. Windows does this, and MS's design guides imply this is the right thing to do. o Document race between kthread_exit(0) and kldunload's unmapping of pages that John Baldwin and I discovered. o Debounce the CSC interrupt a little better. o When a 16-bit card is inserted when we don't have a pccard child, warn about it better. Ditto for 32-bit card. o Ack ALL the interrupt bits that we get, not just 0x1. o maybe a couple minor style nits corrected.
