what happens if we run out of bats?
Then it returns NULL and the caller must handle it. The board port
maintainer needs understand the board/CPU/SoC and not depend on more
BATs than are available. They also need to understand that there is a
tradeoff between BATs for IO and BATs for RAM. If t

register and early text because it allows mappings to devices to be setup
early in the boot process where they are needed, and the mappings persist
after the MMU is configured.
