It's possible.  Could you try Rev 4787 & 4788 to make sure, then send me the
logs from both?  I'm also interested in the coreboot_ram.map files.

There shouldn't have been any.  Hopefully everywhere it was (TOPK) it is now
(RAMTOP >> 10) and everywhere it was (TOPK<<10) it is (RAMTOP).

Thanks for helping track it down.
