This port failed to gain traction and probably only a couple Wii consoles
ran FreeBSD all the way to single user mode with an md(4). IPC
support was never implemented, so it was impossible to use any peripheral
Any further development, if any, will happen at https://github.com/rpaulo/wii.

Open Firmware-centric:
- Keep the static list of regions in platform.c instead of ofw_machdep.c
- Move various merging and sorting operations to platform.c as well
- Move apple_hacks code out of ofw_machdep.c and into platform_powermac.c,
where it belongs
- Move CHRP-specific dynamic-reconfiguration memory parsing into
platform_chrp.c instead of pretending it is shared code

When CPU becomes idle, cpu_idleclock() calculates time to the next timer
event in order to reprogram hw timer. Return that time in sbintime_t to
the caller and pass it to acpi_cpu_idle(), where it can be used as one
more factor (quite precise) to extimate furter sleep time and choose
optimal sleep state. This is a preparatory change for further callout
improvements will be committed in the next days.
The commmit is not targeted for MFC.

reach single user mode using a memory disk device as the file system.
This port includes the framebuffer driver, the PIC driver, a platform
driver and the GPIO driver. The IPC driver (to talk to IOS kernels) is
not yet written but there's a placeholder for it.
There are still some MMU problems and to get a working system you need to
patch locore32.S. Since we haven't found the best way yet to address that
problem, we're not committing those changes yet. The problem is related to
the different BAT layout on the Wii and to the fact that the Homebrew
loader doesn't clean up the special registers (including the 8 BATs)
before passing control to us.
You'll need a Wii with Homebrew loader and a TV that can do NTSC (for now).
