provided, for example, on the PowerPC 970 (G5), as well as on related CPUs
like the POWER3 and POWER4.
This also adds support for various built-in hardware found on Apple G5
hardware (e.g. the IBM CPC925 northbridge).

Convert PowerPC AIM PCI and nexus busses to standard OFW bus interface. This2008-10-14T14:54:14ZNathan Whitehornnwhitehorn@FreeBSD.org2008-10-14T14:54:14Zurn:sha1:51d163d3e91cbf4fe782352c88c0dc6f37015b47
simplifies certain device attachments (Kauai ATA, for instance), and makes
possible others on new hardware.
On G5 systems, there are several otherwise standard PCI devices
(Serverworks SATA) that will not allow their interrupt properties to be
written, so this information must be supplied directly from Open Firmware.

Replace all calls to minor() with dev2unit().2008-09-27T08:51:18ZEd Schoutened@FreeBSD.org2008-09-27T08:51:18Zurn:sha1:6bfa9a2d66dd0e00182017d6741d44e54d0b2cca
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.
This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

Redefine bus_space_tag_t on PowerPC from a 32-bit integral to2007-12-19T18:00:50ZMarcel Moolenaarmarcel@FreeBSD.org2007-12-19T18:00:50Zurn:sha1:de2fa7b8af9fcb685150e9efd6831ee0d126f00d
a pointer to struct bus_space. The structure contains function
pointers that do the actual bus space access.
The reason for this change is that previously all bus space
accesses were little endian (i.e. had an explicit byte-swap
for multi-byte accesses), because all busses on Macs are little
endian.
The upcoming support for Book E, and in particular the E500
core, requires support for big-endian busses because all
embedded peripherals are in the native byte-order.
With this change, there's no distinction between I/O port
space and memory mapped I/O. PowerPC doesn't have I/O port
space. Busses assign tags based on the byte-order only.
For that purpose, two global structures exist (bs_be_tag and
bs_le_tag), of which the address can be taken to get a valid
tag.
