There is some duplication of information between board/atmel/readme.txt
(which also covers SAMA5 Xplained platforms) and
board/atmel/xplained/readme.txt.

Perhaps board/atmel/xplained/readme.txt should be removed entirely, and
board/atmel/readme.txt contain all the information?

Seems like board/atmel/readme.txt covers how to flash on NAND, while
board/atmel/xplained/readme.txt covers how to use a SD card based
booting. Definitely not very clear when looking at the readme.txt
location.

Another possible (but future, and unrelated) improvement is to use
genimage to generate a ready-to-use SD card image, which automatically
contains the VFAT and ext4 partitions.

Thanks!

Thomas
