Both schematics and my tests on v1.0 board confirm that this fix is ok.
However we haven't yet got the ACK from Jagan, the original submitter
of this dts file. FWIW discussion was mostly about the problems with
his setup and not about the fix itself.

Jagan,
did you have a chance to resolve the issues with your setup and verify
that boot from sd-card is fixed by this patch ?

Sergey
