dreamplug patches have not been accepted into mainline because the proper way to do it (which globalscale didn't do in the binary they provided) is with a new machine id. This is already reserved [1]. U-boot shouldn't use the new mach-id until it is in mainline Linux. Linux won't accept new ARM boards unless they are moving towards device tree. I submitted an RFC patch to add dreamplug support to Linux (no devicetree) [2] and I'm currently learning devicetree [3]. Any pointers anyone might have for ARM devicetree would be much appreciated. ;-) You can do item #3 on your bullet list with the patches I've submitted to u-boot [4]. items #1 and #2 require reading from flash to ram, then hexdumping the ram to stdout over serial and capture to a file on your computer. Then, revert it to binary. See here [5]. hth, Jason.
