-- Frank Mandarino fmandarino(a)endrelia.com Endrelia Technologies Inc. Toronto, Ontario, Canada The ASoC machine drivers for this board were only provided as examples for the new AT91 ASoC platform driver. Since the ETI-B1 board is proprietary and there are other AT91 ASoC machine drivers available, it makes sense to remove these drivers.
