As a follow-up, I really dislike fdt_high/initrd_high being set such
that we disable relocation, that just leads to down the line
"kernel/initrd grew, was overwritten".  We should be using bootm_size to
define the area in memory that everything can reside in, so that U-Boot
can be smart about relocations.
