Anyway, is it the fix known ? Should it be done in U-Boot or FSL-3.10 kernel ?
I have just started debugging, so I am not sure at this point.
Internal FSL U-boot also disables VDDPU, but it does not cause the hang when GPU driver is loaded.
As I said the SabreSD case seems to be solvable adding support for the PMIC. I did it for our customer board and it works however it does not solve the case where the board does not have a PMIC. One of our customer is in that case and for now I don't know a solution for it.
The PMIC way that has been done in FSL fork is quite ugly as it does not use the PMIC API but can be used as a base for it.
