I agree with not abusing small_flash for that. It has a clear defined
meaning, and shouldn't have unrelated side effects.
I think a new opt-in symbol for those targets with hardware
virtualization support and/or beefy enough cpus would make more sense.
Those virtualization options (probably) don't come for free, they will
have also a memory and performance impact even when not actively used.
How much that is (and if this assumption is true) would be nice to
have in the PR/patch for it.
