Stefano Babic 8edcde5e4e mkimage: Add Freescale imx Boot Image support (imximage)
This patch adds support for "imximage" (MX Boot Image)
to the mkimage utility. The imximage is used on the Freescales's
MX.25, MX.35 and MX.51 processors.

Further details under doc/README.imximage.

This patch was tested on a Freescale mx51evk board.
