[U-Boot] decompile u-boot.bin file

[Heer Lorcan]

Hey,

have this iriver cover story.
would like to hack the damn thing, since it's linux based and could do some
work.
add some options, delete others.
have gotten the firmware decompressed from a EB05.HEX file to a very nice
extended directory. the rootfs.cramfs is also decompressed.
just leaves me the few files,
*.feb -> unknown format
the zImage
and the u-boot.bin

could any of you here help me out with the u-boot.bin?
kind regards,
