"support" status here means officially advertised by the distro docs
and also (manually) tested that it works for them.
In the v2, I'll add the links for the documentation.

So, in these patches I'm proposing:
<os>
  <firmware arch='all|x86_64|armv7l' type='bios|efi'
supported='true|false'/>
</os>

When taking secure boot into account, I'd extend what we have now and
add:
<os>
  <firmware arch='all|x86_64|armv7l' type='bios|efi'
supported='true|false' secure='true|false'/>
</os>

What do you think about this?


One other thing that you didn't raise but that I'm not exactly
convinced on how to do is how to expose the bios support.

I may be mistaken but I don't think any app would actually want to
check whether bios is supported (although apps would want to check when
bios is *not* supported). So, for now, I'd *not* add info about bios
and would have to add an API for returning the supported types and
another one for returning the *non* supported types. It's either this
or start adding info in a bunch of entries about bios being supported
(and here I can see some issues because bios may not be exactly the way
to go for different arches ... well, a lot of testing/research would
have to be done anyways).

What's your opinion/preference on this?
