powerpc/pasemi: Add Nemo board device init code. (656fdf3a) · Commits · 戴 / test

Add routines for Nemo specific devices to init at boot time, these being board level power-off and SB600's rtc. Also add a run time variable to prevent these being activated if we boot on a reference board. Signed-off-by:
