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.

branches: 1.2.2; 1.2.4;
wii: Add support for passing boot options to the kernel.

evbppc: Add initial support for the Nintendo Wii

wii: Add support for using a USB Gecko as serial console.

The USB Gecko is a Wii/Gamecube development tool which connects to the
GameCube memory slot of the Wii and a USB port of a computer. The USB
port exposes an FTDI serial port on the computer side of the connection.

EXI commands sent from the Wii to the USB Gecko can read and write bytes.
Wire this up to form a simple serial console when the device is detected.
Use WSDISPLAY_MULTICONS to allow for simultaneous use of the USB Gecko
and the framebuffer console.

wii: Use GX to accelerate RGB to YUY2 conversion.

Allocate a 640x480x32 RGB buffer in memory, and when not in EMUL mode,
use the CPU to copy from the RGB buffer to EFB (taking advantage of the
pixel engine to do RGB -> YUY2 for us) and then use the GX to copy from
EFB to XFB.

Not only does this improve performance significantly in X, it also results
in better colour reproduction. The previous software method employed by
xf86-video-wsfb had some corner cases where eg. dark colours would display
as bright pink.

wii: Allow the RESET button to reboot system when halted.

branches: 1.9.2;
wii: Early init for DVD support

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.

Measured CPU frequency before this change:
[ 1.000000] cpu0: 750.00 MHz, 256KB WB with ECC L2 cache

Measured CPU frequency after this change:
[ 1.000000] cpu0: 729.00 MHz, 256KB WB with ECC L2 cache

Move the at-shutdown call to resettodr() from cpu_reboot() to kern_reboot().

It's a small step, but it's a step.

Use usable MEM2 fields in Broadway / IOS Global memory locations to
determine available memory.

the FAT partition of an SD card in the bootmii directory. The bootloader
doesn't have a user interface, it simply loads a kernel from the first
FFS partition it finds on the SD card.

Debug logs are printed to a USB Gecko device in either memory card slot
if present.

wii: rtcsram: Ignore counter bias when reading/writing RTC.

Counter bias is used by system menu as an offset from the RTC for the
time displayed in the Wii's OS. Since Wii doesn't have a concept of time
zones, this bias is useless to us.

Due to a previous bug with parsing SRAM data, the bias read was always 0.
Now that the bias is read correctly, we're reading and writing
preposterous times -- remove the bias from the calculation to restore
the previous setting.

So with this change, the RTC is always in UTC and the Wii system menu
date/time settings adjusts the bias as an offset from that.

Change todr_chip_handle::cookie -> todr_chip_handle::todr_dev, and
make it a device_t. Upcoming functional changes will require the

Nothing was using the old field, but I decided to keep it around just
in cause something needs it in the future.

wii: Add support for GameCube controller sockets.

A new driver is introduced for the Serial Interface that exposes the four
GameCube controller sockets as uhid(4) devices. The report format and HID
usages of these devices attempts to mimic the official USB GameCube
controller adapter.

wii: Use GX to accelerate RGB to YUY2 conversion.

Allocate a 640x480x32 RGB buffer in memory, and when not in EMUL mode,
use the CPU to copy from the RGB buffer to EFB (taking advantage of the
pixel engine to do RGB -> YUY2 for us) and then use the GX to copy from
EFB to XFB.

Not only does this improve performance significantly in X, it also results
in better colour reproduction. The previous software method employed by
xf86-video-wsfb had some corner cases where eg. dark colours would display
as bright pink.

branches: 1.1.2; 1.1.6;
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: 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.

branches: 1.2.2; 1.2.4;
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
