Note that this is a device tree enabled platform so there is no 
/proc/atags.  I'm happy to test any related patches on our platform, but 
kexec isn't something we really use.

This is almost certainly the problem as the ARM kexec code doesn't have FDT
support afaict, so the new kernel doesn't think it has any memory. Can you
try hardcoding a command line into the kernel image which specifies the
memory layout?

That does the trick.  It now gets to the point where the platform code 
starts looking for platform specific parts of the device tree (which it 
can't find) so I'd call that a success.

Feel free to add a Tested-by: Jamie Iles [off-list ref] if you 
like!
