Hi Jason,

Bringing this point back...

Is this a hard request from your side?

This fwctl here is mostly the front-end mirroring FW, but still using directly
the xe interfaces there for the communication with the pcode FW.

Also, there are changes coming to pcode interfaces there to align better with
i915 and xe code sharing. I believe it would be easier and beneficial to have
this under DRM subsystem near xe and pcode code.

But, please, let us know your thoughts here.

Thanks,
Rodrigo.
