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.
