ASoC itself is platform independant. It does require drivers for the
CPU, CODEC and board that it is to be used with. You mentioned that you
are using an Atmel processor which does have CPU side support in current
Linux versions though the ADC you mentioned doesn't.

ASoC is part of the standard Linux kernel, just build the kernel as you
would normally. As I said in my previous mail people working with the
same embedded Linux distribution as you are would be the best people to
ask about this, it is not at all ASoC or ALSA specific.
