Use gpsign to produce an image of u-boot.bin signed with
a Configuration Header for booting on OMAP processors.
This allows U-Boot to boot without the need for an
intermediate bootloader (e.g. x-loader) if it is written
on the first sector of the boot medium.
This only works for some media, such as NAND. Check your
chip documentation for details. You might also want to
read the documentation of gpsign, the tool that generates
the .ift image, at:

The Configuration Header (CH) config file defines the
desired content of the CH for the signed image.
It usually contains external RAM settings and
possibly other external devices initialization.
The omap-u-boot-utils software contains example
configuration files for some boards:
