The Tegra210 L4T bootloader ram training will corrupt the in-ram kernel
dt if no reserved-memory node exists. This prevents said bootloader from
being able to boot a kernel without this node, unless a chainloaded
bootloader loads the dt. Add the node to eliminate the requirement for
extra boot stages.

I test this platform and don't see any problems. I assume that this would prevent the board from booting.

What bootloader are you using? Is this from a particular L4T release?
