Remove unnecessary include of <sys/malloc.h>.

KNF. No functional change.

Redefine bpf linkage through an always present op vector, i.e.
#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.

Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

Remove struct sbusdev and related functions sbus_establish() and sbusreset().
They are derived from 4.4BSD/sparc and have been there since initial import
of NetBSD/sparc in 1993, but the struct sbusdev is almost unused for years,
nothing calls sbusreset(), and all (*sd->sd_reset)() functions look bogus.

Suggested by mrg@ and martin@, and tested on SS1+ and SS20.

sbus_establish() should take device_t self for the device itself,
not device_t parent even if sbus is grandparent of the device,
otherwise (*sd_reset)() callbacks will be called with an wrong device_t.
Even in such case, sbus_establish() looks for an sbus though device tree.
XXX: (*sd_reset)() isn't called anyway, and these stuff seems really bogus.

Fix botch on device_t/softc split caused by awful casts around
registration of (*sd_reset)(device_t) in struct sbusdev via sbus_establish().

XXX: (*sd_reset)() in struct sbusdev seems called from only sbusreset(),
XXX: but there is no function which calls sbusreset()???

Remove clause 3 and 4 from TNF licenses

machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h

Rename PROM_getprop*() => prom_getprop*().

Replace myetheraddr() by prom_getether().

Remove ancient DDB-dependent `hide/integrate'.
Simplify lewrcsr/lerdcsr; read-back after write doesn't hurt on sun4 so
skip the cpu type test in generic kernels.

branches: 1.16.6;
Remove the `flags' argument from bus_intr_establish().

Add trailing ; to CFATTACH_DECL.

Use CFATTACH_DECL().

Declare all cfattach structures const.

Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver. The cfdriver is then looked
up in a list which is built at run-time.

Get rid of unnecessary BUS_SPACE_MAP_LINEAR.

Get rid of `bus_type_t' and use BUS_ADDR() (in sbus_bus_map()) to construct
a `bus_addr_t' to pass on to bus_space_map().

Drop `va' argument from sbus_bus_map(); it should not be used by MI Sbus
drivers.

add RCSIDs

getprop* -> PROM_getprop*

branches: 1.7.2; 1.7.4;
use _KERNEL_OPT

branches: 1.6.2;
Add a `device class' interrupt level argument (from machine/intr.h)
to bus_interrupt_establish().

It's currently only used in sparc64/dev/psycho.c to assign a CPU interrupt
level to devices in PCI slots.

branches: 1.5.4;
Remove old-style boot device recognition.

Check presence of Sbus interrupt properties before using them.
Only one case is known to trigger this omission: a Sparc Classic
configured as X terminal.

branches: 1.3.12; 1.3.18;
Use bus_space_*() to access device registers.
Add `esp' and `le' DMA engine.

Assign my copyrights to TNF.
