   Thanks for the follow up on this, but I don't think that there were only
very few rev1.0 boards delivered. These were the boards bought from
distributor and during the time span of many weeks.

   I don't know the details and the impact of this patch exactly but
if the patch will break any rev1.0 board I don't think this would be
acceptable. There are definitely enough number of rev1.0 boards
made generally available (not specifically for early adapters etc)
that we should not break u-boot running on them.

   Sorry, but this is a bit irrelevant here. I'd expect u-boot mainline
does not necessarily follow what your SDK stops supporting. If
u-boot supported rev1.0 boards and if there are still many of
  them out there I see no reason to break this.
