Notes:
•
LID# and SLEEP# signals are not natively supported on the SoC. They instead connect to GPIO pins
simulating their behaviour.
•
*VGA is by build option, in place of DDI2
•
eDP x4 lanes is by build option, in place of LVDS
•
SD signal is muxed with GPIO, switching controlled by BIOS setting (see section 3.3.14)
•
PCIe bridge IC is by build option to support more than 4 PCIe x1 (e.g. PCIe lane 4)
