Sent you an email earlier off the ML  I made many of the sme poiints.  We're in
agreement.  The devices are too dissimilar in operation.  Just some shared
registers.

Of this I'm sure.

He just showed me how to avoid the need for any bch calculations altogether,
relying entirely on his in-kernel algorithm.  It's been tested.

I appreciate that!

I'll parse your review in its entirety once I'm done with the cleanup of the ecc
handling.  Thanks for taking the time to go through the code.  I also want to go
through your G3 driver code in more detal.  I think we may have a lot of notes
to compare.  And I'm anxious to resume looking through my P3 test code and notes
from 18 months ago.  I should have some good info for you.  The G3 might just be
a P3 with double the capacity.  I already see that the addressing is the same.

Thanks,
Mike
