configuration of devices logically attached to the ISA bus:
* Change the isa_attach_args to have arrays of io, mem, irq, drq
resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
isa_attach_args. If either of these members are non-NULL,
direct configuration of the bus is being performed. Add an
ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
direct configuration is not being performed and the probe fucntion
is returning success.
* Adapt device drivers -- currently, all driver probe routines return
"no match" if ISA_DIRECT_CONFIG() evaluates to true.
for 12-bit addresses. This causes PCMCIA cards mapped at 0x400 and higher
to not function properly. However, the range 0x300-0x3ff causes some
laptops (e.g. the NEC Versa 6030X) to hang if cards are mapped there.
So, after some experimentation, we compromise. If the probe discovers
a 12-bit address bus, don't trust it. Instead, use the range 0x330-0x3ff.
This has been shown to work on the laptops that the 0x300-0x3ff range is
known to fail on.
intr_alloc_mask) into one place, comment them, and defopt them.
- Rename pcic_intr_alloc_mask to pcic_isa_intr_alloc_mask, since it's
an ISA-specific thing.
- When allocating/establishing the PCIC's interrupt (for card events),
do error checking, and pay attention to the intr_alloc_mask.
for the built-in SCSI on NEC Versa docking stations, and if a card
allocates that IRQ, it will never get interrupts. This caused the
default kernel to not work on these laptops, as IRQ 10 was often the
first free IRQ.
Instead, print a diagnostic and return. (Some drivers do this already.)
Also, normalize the diagnostic message, and fix some places where the
printfs were getting ugly.
