Allow to build ARM configuration with support for initializing hardware domain.
On ARM it is only possible to start hardware domain in multiboot mode, so
dom0less support is required.
I don't follow this. Late hwdom is supposed to be started by a (minimal)
toolstack iirc.
Yes, on x86 it's started by toolstack. This is not supported on ARM.
However dom0less can already handle hardware domain initialization on
ARM, without much of an additional changes.
Yet that's not "late hwdom" then, but "separate hwdom and ctrldom" or some
such.
indeed, "separate hwdom and ctrldom" more accurately represents what I
was trying to do when using this late hwdom feature.
