Hi Wolfgang:

 Up to my knowledge, u-boot can load .bin, .elf and .srec binary files.

.bin files are just raw binaries with no location info. When you load
this file the offset mean the "absolute address"
.srec files have info about location. The offset really mean offset,
and is relative to the address specified in the file
.elf files have info about location, but right now (UTMK), u-boot does
not support offsets.

I think that his patch is enough, other binaries should not be fixed
because there is no reason to locate a .bin file in the address -0x234


  What do you think?


           Best regards
