to the screen on which they are being called. The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place. There are no functional changes
yet.
Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.

and others to avoid providing PCI I/O space at address 0.
Iyonix, however, needs to provide PCI I/O space at 0.
The others require I/O space to be offset in part due to a bug
work-around in wm(4) which requires that I/O space access be used
to reset the controllers. If I/O space is mapped at zero, the card
claims, but ignores, the transactions, and the controller doesn't
get reset properly and can't then be used.
kernel config option CPU_XSCALE_PXA2X0 is now obsoleted by
CPU_XSCALE_PXA250 and CPU_XSCALE_PXA270. If both of them are defined,
CPU is determined run-time.
-Wcast-qual differently, by instead changing the signatore of those
"functions" to take a "volatile struct timeval*" instead of a
"struct timeval*". Many places, these functions are called with
&time, and time is declared as volatile in <sys/kernel.h>. This
way we can get rid of all the ugly casts which now also triggered
warnings, and caused more code to be added to work around the
problem.

Many thanks to Hiroyuki Bessho for testing this driver with the new
aurateconv interface, as I no longer have access to the hardware.

- don't use managed mappings/backing objects for wired memory allocations.
save some resources like pv_entry. also fix (most of) PR/27030.
- simplify kernel memory management API.
- simplify pmap bootstrap of some ports.
- some related cleanups.
I/O registers that are used in early start-up stage. Also stop using
special bootstrap-time-only bus_space_map function in {lubbock,g42xxeb}_machdep.c.
This makes initarm() for them a bit simpler, and gives us smaller diffs
to other evbarm platforms.
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.
interrupts; some boards actually use those GPIO pins as external
interrupt sources.
Instead, assign soft interrupt bits to on-chip sources which are
not used by the IXP425 port.
In the interrupt dispatch loop, make sure to handle any pending interrupts
which came in while we were dealing with the first interrupt(s), and which
are enabled at the current spl.
This fixes a problem where the intr_enabled/hw mask is not updated to
allow pending interrupts through until the next splx(). In some case,
interrupts could be delayed until the next clock tick.

the functionality of ixp425_bs_tag.
- Add missing stream_{read,write}_1 ops to ixp425_bs_tag.
- Re-work the delay() implementation to use the free-running Time-
Stamp counter. This removes the need to bootstrap TMR0 early on.
