Since v1:
- Dropped unrelated / irrelevant patches
- Addressed Pierrick comments
- Added R-b tag
- Only considering machines, not CPUs.

Hi,

At this point this series is mostly a draft for Pierrick.

After introducing the generic TargetInfo API [*], we implement
the ARM variants, then use the API to remove target-specific code,
allowing to eventually remove the target-specific arm_ss[] source
set in meson.build, having all objects in arm_common_ss[].

Regards,

Phil.
