Log Message:
Pull up following revision(s) (requested by jmcneill in ticket #1057):
distrib/utils/embedded/conf/evbppc.conf: revision 1.4
sys/arch/powerpc/oea/cpu_subr.c: revision 1.111
sys/arch/evbppc/wii/pic_pi.c: revision 1.2
sys/arch/evbppc/conf/WII: revision 1.9
sys/arch/evbppc/wii/dev/bwai.c: revision 1.4
wii: Simplify Processor Interface pic code.
wii: Audio playback improvements.
Instead of resetting the byte counter for every block (which is racy),
increment the interrupt timing register by the exact byte count for
each block. Should do better at keeping things in sync.
powerpc: Identify Broadway CPU.
Use hex to report Broadway revision and ignore TAU as it does not exist
on this processor.
wii: Remove some options to save memory.
wii: Disable ntpd by default.
It takes up a lot of memory.
