Thanks, I've applied the entire patch series. To be honest, I was not
sure with your change moving from the mainline U-Boot back to the
Xilinx-specific U-Boot. In general, we try to use the mainline version
of the Linux kernel or U-Boot. But since the patches have been sent
some time ago, and nobody else commented, I took your approach.

One thing that would be good it to add genimage support to
automatically generate the SD card image with the VFAT partition.

Also, why is an initramfs use, rather than a more standard filesystem
like ext4 on a second partition of the SD card?

Thanks!
