Do you have a branch with both patches applied? Or maybe it is simpler
to wait for the first one to hit mainline and upgrade the u-boot recipe
at that time.

I'm a bit concerned that the second patch will actually change the
behaviour of the am335x_evm config, switching from reading the env in
nand to that file in the first FAT partition. Do you want to change
that?
