Here is a patch that adds file_offset to load_image command.
This allows loading 'bin' regions that do not start at 0x0 file offset.
I use this to create a simple flash driver in tcl. It load chunks of the
bin file to memory and burn them to flash. This is saved me a quite a
bit of time as I did not have to write a full flash driver in openocd.
