FWIW, I really don't like this as this is just for a downstream kernel. For the upstream kernel the firmware should be loaded by the kernel itself. But unfortunately, there is no development there. (I have some half baked patches though and can confirm, that firmware loading is working from linux). Instead of this I'd like to see some work to support the DP PHY in upstream linux as this is really the last missing piece to get graphics working. Now this is purely board related code, so it is probably fine. But in the past the handling of purly downstream stuff was removed from upstream u-boot anyway in favor of the upstream method. i.e. fixup of the ls1028a-gpu node. -michael
