    sys/pccard           pcic.c pcic_isa.c pcicvar.h 
  Log:
  Next step towards pcic_pci: the ability to allocate mapped memory in attach.
  
  o Introduce flags word to the softc.  This will be used to control various
    aspects of the driver.  Right now there are two bits defined, PCIC_IO_MAPPED
    and PCIC_MEM_MAPPED.  One for ISA cards that are I/O mapped, the other is
    for PCI cards that are memory mapped.  Only the ISA side is implemented
    with this commit.
  o Introduce a pcic_dealloc which will cleanly dealloc resources used.  Right
    now it is only supported when called from probe/attach.
  o Keep track of resources allocated in the pcic_softc.
  o move pcictimeout_ch to the softc so we can support multiple devices
    in polling mode.
  o In ISA probe, set PCIC_IO_MAPPED.
  o Introduce and compute the slot mask.  This will be used later when
    we expand the number of slots on ISA from 2 to 4.  In such a case, we
    appear to have to use polling mode otherwise we get two different cards
    trying to drive the same interrupt line.  I don't have hardware to
    test this configuration, so I'll stop here.
