First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

Introduce a function to check the "status" property of an OFW node, and use it
to avoid attaching disabled or failed devices.

Introduce a function to check the "status" property of an OFW node, and use it
to avoid attaching disabled or failed devices.

This should make it possible to manually deconfigure devices on mid-range and
high-end servers like the V880 using the "asr-disable" PROM command, and make
OpenBSD avoid using hardware that has been detected as faulty by the POST or
OpenBoot Diagnostics.

Add getpropspeed(); a function which decodes a property describing a serial
port configuration and returns the configured speed.

use the right capitalization for `SBus'

Replace code that tries to find the boot device by pretending to walk the

Replace code that tries to find the boot device by pretending to walk the
device tree and matching locators in the bootpath string components with
code that tries to match the PROM node of the devices to bootpath components.
This way we don't need a list of possible boot devices that needs to be
tweaked whenever we try to support new Sun hardware (or when dlg plugs a
new fancy storage controller in a sparc64 machine).

Tested by many.

match fiber channel portwwn/lun to it's bootpath variables

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

Decruftification.

We will never have a.out kernels.
We will never have 32-bit kernels.
We will never have sun4c, sun4 and sun4m support in the sparc64 kernels.
We don't need support old netbsd libc.

The cpu will never be identified as some of the sun4c and sun4m types.
We don't need the gazillion of fields in cpuinfo that the sparc port uses.
Just generally remove dead code.

This is just a first step in making this meess readable.

Final __P removal plus some cosmetic fixups

First round of __P removal in sys

grab the "compatible" prom property and use that for searching the device
tree as well as the "name". This allows us to differentiate 'sd' and 'wd'
pretty easily (and makes it less ambiguous).

implement autoconf mechanism using device_register(); from NetBSD.
