[U-Boot] [PATCH] [v2] powerpc: 'monitor' environment variable contains full video configuration

Looks as if this was a Freescale specific implementation?

Can this not be turned into generic code, usable for other boards /
systems as well?

Please see the discussion we had about video modes for the i.MX
systems.

I want to see handled most of this with generic code, not with
processor / architecture specific one.


Best regards,
