I wonder how many work we want to do to try to make the auto-region
path more reliable for complex setups (interleaving being one example).
In other paths, in particular when there is some implied use-case for
the device, we already take the opinion the BIOS should do nothing.
Should we draw a hard line on when that should be the official opinion?
i.e. auto-decoders should be intended for trivial SysRAM regions only
(especially given that a user can't even select zone-isolation except
via a global kernel build option that affects all hotplug memory)
