The x-loader 1st stage bootloader for OMAP includes a tool to generate
images to allow booting at least OMAP 35xx parts from MMC/SD and NAND
memories.

http://gitorious.org/x-load-omap3/mainline/blobs/master/Makefile (see
the x-load.bin.ift target)
http://gitorious.org/x-load-omap3/mainline/blobs/master/scripts/signGP.c
(the utility itself)

signGP doesn't have a lot of documentation in it for what all the
magic values mean.  You can use section 25.4.8 in the OMAP tech ref.
manual to decrypt the structures.
