jmcneill | Improve delay() accuracy on Nintendo Wii.
The PowerPC delay() implementation converts the timebase frequency to
a number of nanoseconds per tick and uses that value to compute the
delay interval. On the Wii's Broadway processor with a timebase
frequency of 60.75 MHz, some precision is lost as each tick is
approximately 16.46 nanoseconds. The end result is that we sleep for
approximately 2.875% longer than necessary. This also has an impact
on CPU speed calculation on Broadway, which incorrectly reports itself
as 750MHz instead of 729MHz (2.875% faster).
Fix this by introducing an (optional) ticks_per_msec variable that can
be set by the platform and allows delay() to improve the accuracy of
longer delays.

jmcneill | wii: Support loading the kernel from boot2
Improve hardware initialization steps so the NetBSD kernel can be launched
directly from boot2 and does not rely on any other PPC software to setup
the hardware.

Move the at-shutdown call to resettodr() from cpu_reboot() to kern_reboot().
It's a small step, but it's a step.

powerpc: oea: Fix prefetchable mappings
Prefetchable mappings need PMAP_NOCACHE to get write-combine semantics.
powerpc: oea: Decode IBM750CL L2 cache information.
sdmmc: add support for optional delay after register write
wscons: Add HOLLYWOOD display and YUY2 pixel format types
wsfb: add support for optional "devcmap" property
A hardware driver can supply a pointer to a 16x 32-bit array to override
the default rasops device colour map in the "devcmap" property.
ehci: add EHCIF_32BIT_ACCESS flag to force 32-bit MMIO
fix comments: HID0 ICFI/DCFI are "flash invalidate", not "flush invalidate"
powerpc: fix delay for large (> ~5sec) values
When calculating the target timebase, promote '1000' on the RHS to ULL
to force 64-bit calculation, otherwise 'n * 1000' will overflow.
usb: increase USB_PORT_RESET_RECOVERY from 10ms to 20ms
I changed this from 250ms to 10ms back in 2021 based on a similar FreeBSD
change, but it seems to be a bit too aggressive for some platforms.
evbppc: Add initial support for the Nintendo Wii
wii: support RB_POWERDOWN
build fix: use dd with count=1 for compat with NetBSD dd(1)
wii: Add NTSC 480p support.
In addition to this, add VIIO_{GET,SET}REGS ioctl support to allow for
poking at video interface registers from userland. This is helpful for
debugging display issues.
wii: Add 128x48 icon to SD card image
wii: Fix a comment
wii: Add drivers for Broadway DSP and Audio interface.

wii: Add screenblank support.
wii: Use screen dimming register for screen blanking.
wii: Add GPIO, I2C, and basic A/V encoder driver.
wii: Use A/V encoder volume controls instead of using a software filter.
wii: Simply DSP driver - no interrupt handler required.
wii: provide device names to intr_establish
wii$ intrctl list
interrupt id CPU0 device name(s)
pi irq 14 64769* hollywood0

hollywood irq 39 58907* sdhc0
hollywood irq 40 4* sdhc1
hollywood irq 49 0* resetbtn0
pi irq 5 0* bwai0
wii: Add support for passing boot options to the kernel.
wii: Add External interface bus and RTC support
wii: Remove objcopy after kernel build.
HBC will do the right thing.
Add wsvt25 entries (off by default) for ttyE0-ttyE3.
Add support for "PAL" (576i) mode on Wii.
