I realise you don't want to enable this as it's breaking some people's systems, but could we add a new boot parameter to force it for working systems? Or check against a black list maybe?

Hi
Curious to know what this means for folk that have newer Raven1 boards that didn't have issues loading the firmware
You won't get ABM I think. ABM is the automatic backlight management.

[WHY] Some early Raven boards had a bad SBIOS that doesn't play nicely with the DMCU FW. We thought the issues were fixed by ignoring errors on DMCU load but that doesn't seem to be the case. We've still seen reports of users unable to boot their systems at all.
[HOW] Disable DMCU load on Raven 1. Only load it for Raven 2 and Picasso.
