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.
