Any specific reason to set fdt_high to fffffff?
Yes, it prevents U-Boot's annoying habit of moving the DTB from where it
was loaded to some other place. This was especially important in this
case since I was trying to find out exactly which piece of RAM being
over-written caused the issues I was seeing.
Shouldn't this then be part of the default raspberry (2 only?) environment?
Eventually yes. So far, nobody seems to know which areas of RAM are
off-limits (presumably since the RAM is used as a CPU1..3 pen), so I was
experimenting to try and find that out.
