With device tree, there are lots of endian conversions. With v7, those
conversions are a single inline "rev" instruction vs. 10-20 assembly
instructions. Since there is no state maintained in the fdt code, the
conversions are done over and over.
So there's not a hard requirement, but it is something I will always set
and I imagine others with v7 platforms will want to also. I think Tegra
prevents doing this change globally.
