I'd apprciate if you can build a working kernel with
CONFIG_DEBUG_MEMORY_INIT=y and run it with 

	memblock=debug mminit_loglevel=4

in the command line.

If I understand correctly, DEBUG_LL is not an option for these platforms
so if earlyprintk didn't display the log there is not much to do about
it.
