Thanks for checking this. Your changes reflect the fixes I do to solve
conflicts for this patch when merging u-boot-arm.

I had reverse Patch 2/2, but not Patch 1/1. In fact, there are later
commit that does not allow to revert the patch. However, I am confident
that fixes are ok, so I will let in this way.

Best regards,
Stefano Babic
