Maybe not right now, but at least the first one seems fairly generic and
could be elsewhere.

The whole __force thing here seems odd, why isn't the input 'v' just
__le16?

This goes with all the FW loader thing - but that also has all __force.
I'd argue it'd be better to just have separate FW-endian (little endian)
and host-endian structures, even if that duplicates the structure
definitions, but it'll have sparse actually checking the fields were all
converted correctly rather than
