ioremap_bat() is useful for things like mapping SoC internally
memory mapped
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.
Without ioremap_bat(), setting up the MMU would cause the early text
mappings to get lost and mostly likely result in a kernel panic on
the next
attempt at output.

why can't we just do this in ioremap itself?
