Just thinking out loud here, but maybe we shouldn't take this patch. The industrial version, on top of having more memory, also has eMMC. That already mandates a new device tree and configuration if people are going to use it as a boot method. Then again, maybe it's convenient for the users who don't care about eMMC? I dunno. Seems odd either way.
