Benoît Thébaudeau - Feb. 15, 2013, 8:54 p.m.
This image adds a dummy 1024-byte header to u-boot-with-spl.imx in order to get
an image that can be programmed on a NAND Flash page boundary.

This supports only i.MX25/35/51 so far, not i.MX53/6. For the latter, the dummy
header will have to be replaced with a generated FCB header depending at least
on the NAND Flash page size.
