the following patch was just integrated into master: commit a090ae04c285c4086973e826a36fe87dfeb74d9e Author: Damien Zammit <damien@zamaudio.com> Date: Sat May 21 01:56:01 2016 +1000 nb/intel/x4x: Add DMI/EP init The values were obtained from vendor bios at runtime. I am not 100% sure of the sequence required to initiate them, but guessed from the gm45 code. There may be some status bytes needed to be polled during the sequence that is missing, but as I don't have bios writer's datasheet it's very hard for me to know.
