Remove unnecessary <sys/malloc.h>.

#include <sys/bus.h> instead of <machine/bus.h>.

Remove clause 3 and 4 from TNF licenses

Don't use device_private on xx_cd.cd_devs[n],
use device_lookup_private(&xx_cd, n) instead.

We have to use device_private() to get softc from cd_devs[].

Don't forget to initialize sc_dev.

Split device_t and softc for MI mc146818 clock,
and other related misc cosmetics.

branches: 1.4.6;
Move todr_attach(9) calls from each MD attachment to MI mc146818_attach().

Add support for rebooting 7024 and 7025 models. Since I cannot figure
out how to properly reboot these machines, instead we make use of the
auto-poweron-alarm time, and power cycle the machine to simulate a
reboot. This is a hack, but until I get documentation on these machines,
at least you will be able to reboot them.

branches: 1.2.2;
1) Modify pnpbus attachment code to properly decode pnp memory range packets.
2) Modify pnpbus attachment code to record the chipid of the device if it
has one.
3) Change the clock probes to use the chipid, rather than relying on
potentially untrustworthy subtype and interface.
4) Add decoding of memory ranges to the RESIDUAL_DUMP code.
5) Add a we@pnpbus device to allow netbooting and root device detection
from an IBM we ethernet. (it will only work if your firmware detects it)
6) Because I moved the pnpbus probe to occur prior to pci and isa, it
screwed up the root device detection and firmware path building code.
Completely rewrite the fw-path detection code to deal with this.

branches: 1.1.2; 1.1.4;
A bit of clock rototill. It's safer to detect things known by the
residual with the pnpbus probes, than it is to do it with raw isa probes,
so I've replaced the isa mkclock and mcclock code with a pnpbus attachment.

While writing the mkclock code, I realized that on motorola prep machines
the mkclock uses the same port range as the nvram part. (it's actually
the same chip/part). This was causing the nvram not to work on those
machines. Now the nvram code will recognize this, and wire up the
mkclock as well. The mkclock probe is just a stub probe used to
pre-detect the fact that this is one of those machines.
