132580b5af MFp4:
Make the ISA bus keep track of more PNP details.  Plus a minor style
fix while I'm here.  More could be done here, but except for some SBCs
that don't have ACPI, there's limited value to anybody in doing so.

c7974ff135 Fix an endianness issue in pnp_eisaformat(). This corrects printing PnP IDs
on big-endian archs like sparc64, e.g.:
uart0: <16550 or compatible> at port 0x3f8-0x3ff irq 43 pnpid @HEd041 on isa0
is now correctly printed as:
uart0: <16550 or compatible> at port 0x3f8-0x3ff irq 43 pnpid PNP0501 on isa0

There are probably other endianness issues lurking in the PnP code which
however aren't exhibited on sparc64 as the PnP devices there are sort of
PnP BIOS devices rather than ISA PnP devices.

Tested on:	i386, sparc64
MFC after:	1 week

2e63992f34 Note when we're done probing PNP. There's been several reports over the
years of hangs that turned out to be in the PNP code.  Add an explicit end
marker so such hangs are more apparent.

o break lines
o consistantly use 8 space tab stops
o minor grammar nits in a few printfs

d117cb4e19 Handle "identifier strings" right. Each ISA PnP card must have a
mandatory "card" identifier string.  A logical devices on the ISA PnP
card may optionally have a "device" identifier string. Do not confuse
them.

The "card" identifier string is assigned to a logical device as the
default description string when the device is found. (If the "card"
identifier string has not been found, use the EISA PnP ID string.
Strictly speaking, this is an error.)  We will override it when a
"device" identifier string is found later.

c395939120 Rework the ISA PnP driver pnp and the PnP resource parser to fix
the following bugs.

- When constructing a resource configuration, respect the order
  in which resource descriptors are read, in order to establish
  the correct mapping between the descriptors and configuration
  registers.

  1994.  "Clarifications to the Plug and Play ISA Specification,
  Version 1.0a", Sec 6.2.1, Dec. 10, 1994.

- Do not ignore null (empty) descriptors; they are valid descriptors
  acting as filler.
  "Clarifications to the Plug and Play ISA Specification, Version 1.0a",
  Sec 6.2.1.

- Correctly set up logical device configuration registers for null
  resources.
  "Clarifications to the Plug and Play ISA Specification, Version 1.0a"

- Handle null resources properly in the resource allocator for the
  ISA bus.

21c3015a24 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of
  calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

fb0ef52838 Finally merge newmidi.
(I had been busy for my own research activity until the last weekend)

Supported devices:

SB Midi Port			(sbc + midi)
SB OPL3				(sbc + midi)
16550 UART			(midi, needs a trick in your hint)
CS461x Midi Port		(csa + midi)

OSS-compatible sequencer	(seq)

Supported playing software:

playmidi			(We definitely need more)

Notes:

/dev/midistat now reports installed midi drivers. /dev/sndstat reports
only pcm drivers. We need the new name(pcmstat?).

EMU8000(SB AWE) does not sound yet but does get probed so that the OPL3
synth on an AWE card works.

TODO:

MSS/PCI bridge drivers
Midi-tty interface to support general serial devices
Modules

bb2b9030e8 * Add some verbose logging to the PnP parser and fix a couple of bugs.
* Move pnp_eisaformat() to pnp.c, declared in <isa/pnpvar.h>.
* Turn the pnpbios code into an enumerator for the isa bus. This allows
  all devices known to the bios to be probed automatically.

Currently the pnpbios code is dependant on the PNPBIOS option. As the code
is tested more and when more drivers are converted this will be made the
default. I have PnP changes in the wings for fdc, atkbd, psm, pcaudio, and
joy. Sio already works with pnpbios.

336dd1864d Parse resource descriptions which don't have START_DEPENDANT tags
correctly.  This fixes resource allocation for various PnP ed cards but
there are other problems which prevent that driver from working right.

4249382df0 This represents essentially a complete rewrite of the ISA PnP code. The
new system is integrated with the ISA bus code more cleanly and allows
the future addition of more enumerators such as PnPBIOS and ACPI.

This commit also enables the new pcm driver since it is somewhat tied to
the new PnP code.
