With LDO bypass, lower VDDARM and VDDSOC voltages can be supplied as per the mx6 datasheet. I just measured with the scope and the VDDARM/SOC voltages supplied by the 3.10 FSL kernel are below the minimum for the LDO enabled case. So setting LDO bypass in U-boot 'fixes' the issue. We can implement LDO bypass after 2014.01 is out, but for this release let's just revert the VDDPU disable patch. Do you agree?
