[U-Boot] [PATCH v7 19/19] imx: Add u-boot-with-nand-spl.imx make target

Benoît Thébaudeau
2013-02-15T20:54:25Z

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.
