# Note! Dependencies are done automagically by 'make dep', which also
# removes any old dependencies. DON'T put your own dependencies here

This is not really a board made by ITE Semi, but it's very 
similar to the ITE QED-4N-S01B board.  The IVR board is made
by Globespan and it's a reference board for the PVR chip.
