[PATCH-for-10.1 v6 12/14] hw/core: Allow ARM/Aarch64 binaries to use the 'none' machine

Posted by Philippe Mathieu-Daudé 5 months, 2 weeks ago

When we'll start to use target_machine_typename() to filter
machines for the ARM/Aarch64 binaries, the 'none' machine
would be filtered out. Register the proper interfaces to keep
it available.

Ought this use DEFINE_MACHINE_WITH_INTERFACES?
