split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

Do not call setroot() from MD code and from MI code, which has
unwanted sideeffects in the RB_ASKNAME case. This fixes PR/46732.

No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information
as a side effect. Instead call MI rootconf() from MD code which makes
rootconf() now a wrapper to setroot().

Adjust several MD routines to set the global booted_device,booted_partition
variables instead of passing partial information to setroot().

Make cpu_rootconf(9) describe the calling order.

Use deviter(9) instead of accessing alldevs directly. Test-compiled,
only.

Ansify function definitions w/o arguments. Generated with sed.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Fix headers.

Use TAILQ_FIRST(3) and TAILQ_NEXT(3) macro.

Defer _spl0() or _splnone() calls (which enable hardware interrupts)
from cpu_configure(9) to cpu_initclocks(9) on mips ports which use
mips3_clockintr.c:mips3_clockintr() (i.e. CPU INT5 clock) to avoid
hardclock(9) before softclock interrupt is initialized in initclocks().
This should be harmless because initclocks() is a part of configure()
in these days and there is no MI function which expects hardware
interrupts between cpu_configure(9) and cpu_initclocks(9).

Disccussed on tech-kern and port-mips.

Use device_is_a()

Use device_class() instead of accessing dv_class directly.

merge ktrace-lwp.

Change the second argument of config_rootfound() from a string to NULL,
so that we compile with -Wcast-qual.

Centralize the declaration of booted_device and booted_partition.

__KERNEL_RCSID()

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.

branches: 1.2.6; 1.2.8;
Make clock/time handling more accurate:
- Use the CPU count register for more accurate microtime (from
sbmips) and delay (based on an evbmips delay function) functions.
- Schedule the next hardclock interrupt more accurately (from
an sgimips patch by Rafal Boni). Clock drift on one board is
now ~7ppm instead of ~330ppm.
- Purge old pmax-based mcclock code.
- Correctly round off some clock-derived variable calculations.
XXX: Some of this code should be migrated to sys/arch/mips.

A port to the MIPS Malta evaluation board. Currently supports the
MIPS32 4Kc CPU board, with support for the MIPS64 5Kc and the QED RM5261
CPU boards to follow.

The cs4281 audio hasn't been tested, there are some interrupt problems
with onboard the pciide, but all other on-board peripherals work.

The evbmips port will support more MIPS evaluation boards in the future.
