50445038df Change the attach routine so it handles all the known cases that pnpbios 
returns for floppy controllers i/o ports. i.e.

1. 1 range of length 4 (which conveniently "forgets" the ctl i/o port),
2. 2 ranges: 1 of length 4 and the ctl i/o port.
3. 1 range of length 6 which goes to the end of the ctl i/o.

Make this line up with the MI fdc code by mapping in a range of 4 on the
base i/o and then either direct or submapping the ctl i/o. In the one case
where the BIOS lies and says it's not there just map it in anyways. (but note
the fact to the end user).

80195863fc This file is a replicant of hp300. The following is peculair to 
the original HPBSD implementation and HP hardware design.

 * Portions of the last segment of KVA space (0xFFF00000 -
 * 0xFFFFFFFF) are mapped for a couple of purposes.  0xFFF00000
 * for UPAGES is used for mapping the current process u-area
 * (u + kernel stack).  The very last page (0xFFFFF000) is mapped
 * to the last physical page of RAM to give us a region in which
 * PA == VA.  We use the first part of this page for enabling
 * and disabling mapping.  The last part of this page also contains
 * info left by the boot ROM.

Nuke lptpa because that is irrelavant for LUNA.
Put #if defined(M68040) for consistency postponing efforts of LUNA-2.

9c25e9208a Port 'an' driver for Aironet PC4500/PC4800 IEEE802.11 card from FreeBSD. 
This is very adhoc work for IETF meeting.
- Since it seems that 'an' and 'wi' have similar hardware, low level
  functions should be shared.
- There are PCI/ISA cards of Aironet but not supported yet.
- The wiconfig interface is changed so that wiconfig cannot be used.
- 'ancontrol' of FreeBSD is not ported.
- Only infrastructure mode is tested.
- WEP is not supported.

Though I only have an Aironet card, Cisco card should be expected to work.

af2807f9f7 Finally fix this driver to be sensible about the ENDIAN dance. It's not 
quite simply a question of the Qlogic being little endian and having
to have stuff swapped on big endian machines- it also has to do with the
fact that the SBus and PCI DMA layouts are wierd with respect to this.

At any rate, now finally fixed- works on Mac G4, tested it on a SS10
for sparc, checked on alpha to see if I've broken anything, and as
soon as I get another spare afternoon I'll finally install a sparc64
version which should just work (as it'll be like the Mac).
