9da7636a93 Add SUN4U magic to make nell work without things like WI_AT_BIGENDIAN_HACK.
XXX - need to move this (as well as the equivalent sparc stuff added
recently) outa here into sbus_machdep or something. We should not need
to know details of the actual bus_space implementation here.

6833c24639 Separate the sbus bus_space_tag_t used for access to nell hardware from
the self constructed little endian pcmcia bus_space_tag_t used for the
client drivers.

7bd617d237 part one of bus_space(9) fixes to enable bus spaces to override the
bus_space_{read,write}_[1248]() functions, which will allow 16-bit
PCMCIA support to work without additional hacks in MI drivers.
this option is not enabled yet.

12da8a0066 Call interrupt handlers from a soft interrupt to decouple them from the
(sometimes excessive) SPL assigned by the firmware to the sbus interrupt.
Protect access to hardware by splhigh().

de956cbcda Only use one interrupt handler for both status changes and pcmcia IO
intterupts. No more races between the two interrupt handlers, without any
locking, and the driver becomes a bit simpler too.

Use the last bit of the config flags to select between the first and the
second sbus interrupt level the firmware has assigned to us.

06de426449 SIMPLEQ rototill:
- implement SIMPLEQ_REMOVE(head, elm, type, field).  whilst it's O(n),
  this mirrors the functionality of SLIST_REMOVE() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
  this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups

642b1a7163 Remove dummy_splraise() - it is not needed according to Paul Kranenburg.
We may revisit this once a general interrupt queuing mechanism is
available and we can avoid calling the pcmcia cards interrupt handler at
an exsessive IPL.

f61bdee8e7 Get rid of `bus_type_t' and use BUS_ADDR() (in sbus_bus_map()) to construct
a `bus_addr_t' to pass on to bus_space_map().

Drop `va' argument from sbus_bus_map(); it should not be used by MI Sbus
drivers.

dfbd0bc7b8 Shuffle around some initialization code a bit.
Configure power supply on VPP1 at 5V when powering up a socket.
Get rid of stray interrupts.
Make the driver quiet for normal operation when not in debugging mode.

This makes ray0 at nell0 actually work when compiled with RAY_USE_AMEM=1.

ba6fe47ae9 Simplify the way the hardware windows are mapped and adapt the pcmcia
chipset functions acordingly. Initialize timing registers (for now to
the slowest possible setting).

Add some debug output. XXX - clean this up.

This is not ready for prime time, but I can attach ray0 and wi0 now in my
LX.

875bff0962 To make dev/pcmcia work on platforms with 64-bit bus_addr_t and
32-bit bus_size_t (sparc), change the pcmcia_mem_map(9) offsetp
argument to bus_size_t as it is used as a bus_space offset.
