If this helps - I do have some code (including OpenOCD
restoration/debricking files) to add support for smdk6410 based on
v2013.04 u-boot.

As fair as I remember this code was booting till prompt, but was NOT in
a shape allowing mainlining.

Unfortunately, I don't have smdk6410 dev board anymore, so I cannot
help with testing/tunning the HW.
