Remove unnecessary include of <sys/malloc.h>.

split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

branches: 1.47.8; 1.47.18;
Cast the sum of iobase and iosize to long, not just iobase. Avoids size
warnings during build when bus_addr_t is 64 bits.

Do not disestablish the interrupt handler inside of the interrupt
handler! Stops a crash on the HP Pavilion N3270.

Cosmetic: sc->ih is a pointer, so set to NULL instead of 0. Compare
with NULL instead of testing truth.

branches: 1.45.2; 1.45.4;
Misc KNF and cosmetics, and remove unnecessary casts etc.

Use device_private(), proper types or variables for device_t and softc.
(not yet split though)

No crash on gxemul emulating hpcmips mobilepro.

struct device * -> device_t, no functional changes intended.

ansify function definitions

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Separate the namespace for default (ie unspecified) locators used
by the isa.c bus driver and the "address/whatever not specified"
argument passed to leaf device drivers.
The former is "ISACF_XXX_DEFAULT" as generaterd by config(8), the latter
"ISA_UNKNOWN_XXX", defined in isavar.h.
This way we save a dependency of every ISA device driver on "locators.h".

Several changes to eliminate bogus controllers and sockets from being found:

PCIC_VENDOR_NONE: New.
PCIC_VENDOR_CIRRUS_*: Collapse the 2 chips into one vendor ID.

pcic_ident_ok(): Check the ID revision field -- if it's 0, punt.

pcic_vendor(): Check the ID revision field -- if it's 0, or the ID register
is all-1s, assume there is no chip present. (Previously this would return
"Unknown controller" -- which, AFAICT, *never* resulted in a working device.)
Do the Cirrus check only after verifying that we got the Intel ID.

pcic_attach(): Use a priori knowledge of the Cirrus chips to determine the
number of sockets rather than trying (unsuccessfully) to probe. Also, just
blast all of PCIC_INTR -- we do this in pcic_deactivate_card() anyway.

If the frontend passes in sc->irq=0, set PCIC_INTR_ENABLE. Also, don't clear
that bit all over the bloody place

branches: 1.31.2;
interrupt with two rs.

don't need <sys/types.h> when including <sys/param.h>

Add a big comment in the previous section of code...

Back out previous change.
I removed this once before a long time ago, because it's wrong and breaks
PCMCIA on some machines. It also doesn't fix the Multia problems.

Use IST_LEVEL as appropriate. Fixes PCMCIA interrupt problems
on the DEC Multia. From Juergen Weiss <weiss@Uni-Mainz.DE>.

Don't use __hpcmips__, but hpcmips

Update comment.

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

Back out rev 1.7 of i82365_isa.c; 0x300-0x3ff, or even 0x330-0x3ff
is not a reasonable place to allocate 12-bit pcmcia iospace.
It seems to cause conflicts on a large number of modern laptops,
necesitating hand-patching of the kernel (mostly due to
video devices in the upper range of that space).

This will presumably cause problems on the NEC Versa 6030X,
however that appears to be a vastly less common case than
the laptops that are inconvenienced by the current state.

12-bit iospace now uses 0x400-0xfff.

Fix naming think-o.

Fix the same race condition while initializing the socket.

Reorder the usage of intr_establish/intr_disestablish with respect to setting
the CSC_INTR register, to insure that the IRQ is not left floating and enabled
at any point. Eliminates stray interrupts during the IRQ probe.

Allow a flag to be set to force polling for socket events.

I told them not to use IST_LEVEL here. Now PCMCIA works on my AS200. *sigh*

Don't use void * for chipset tags. Bad hacker, no biscuit.

In light of the previous change, whack the clearing of CSC_INTR
again.

The final read of the CSC register does not appear to be needed any
more.

deal with loops that we get stuck in due to unhandled interrupts.

Be more careful with the CSC_INTR register while probing.
Make some output more specific.

only enable interrupts from the controller if the socket is enabled

doh, remove debugging leftover (forcing irq 15 to always be avail).

Cosmetic change; use IRQUNK instead of -1 always.

Make irq probing controled by patchable variable and disable on hpcmips
by default. It doesn't work on hpcmips.

restore irq 10 to pcic_isa_intr_alloc_mask

implement probing for available irqs on non-cirrus pcmcia controllers
including cardbus controllers running in pcic mode

This is the first check-in of CardBus driver. CardBus driver contains
CardBus bus stub, YENTA PCI-CardBus bridge (cbb), 3Com 3C575TX driver
(ex) and Intel fxp driver.

TODO:
o Conform to the KNF more strictly.
o Be unified with pcmcia code as much as possible.
o Add more drivers for CardBus card, such as APA-1480 or USB card.

Oops; PCIC_INTR_ENABLE does something *very* different.

Use the correct interrupt sharing type, and set PCIC_INTR_ENABLE(!).

Add ISAPnP attachment for PCMCIA bus controller; reorganize ISA
attachment to let it share code with PnP attachment.
