[U-Boot] [RFC 0/4] sunxi: Implement transition in environment

[Maxime Ripard]

Hi,

Here is an RFC to implement the transition from a raw environment in
the MMC to a FAT file in the first bootable partition.

This is based in a custom environment method that reuses the mmc and
fat codes as much as possible, and just deals with the fallbacks,
printing a warning when we're using the now legacy setup so that we
can warn our user of the future breakage.

This has just been compile tested, I'm mostly looking for feedback on
the appoach at this point.

Thanks!
Maxime
