Hi Andreas,
Thanks for your work.

This series add atmelimage support to mkimage.
An atmelimage is a quite dumb image type cause it has no real header. The file
is mostly unmodified but the 6'th ARM vector gets replaced by the image size
to load.
Heiko, I know your approach setting the vector in start.S but I think this
solution is a bit smarter. We would need to patch at least 2 start.S files
(arm926ejs and armv7), maybe also the arm920t one too. In fact is the
conversion of executable BLOB to ROM detected executable BLOB something that
should really be done afterwards as all other SoC vendors do.

For this patch set, test ok on sama5d33ek with spi flash and mmc boot.
For nand flash boot, it doesn't support to add PMECC header, so only
works in software ECC or none ECC mode (that means, u-boot flash
boot.bin to NAND flash won't work). So, do you plan to add following patch?
Best Regards,
Bo Shen
