For me as well :)

I think we should continue this as soon as more of you have
an Early Adopter board to really test the software.

I have added a small patch that initializes the McBSP
for the GTM601 and on one of my boards there is no GTM601
installed. Therefore, I could use a scope to see the clocks, framesync
and data when issueing an aplay command.

So the commit ed129f93dfa4683aeb31ac906ed8773afbb3aa56
includes this setup code.

Since there appears to be a soldering glitch of the GTM601 on
my other board, I have not tested if there is real data transmission
when doing a phone call.

I think by end of next week we will get plenty of boards to continue
these tests :)
