I can confirm that Nyan was the first Arm device shipping with
depthcharge. Note that the Exynos devices are all older and shipped
with an old fork of U-Boot that probably handled this very differently
(I believe they had `/firmware/chromeos` but not `/firmware/coreboot`,
so they wouldn't have had a `reg` node and should need no `ranges`).
