x86: Add Advantech SOM-DB5800/SOM-6867 support
Add support for Advantech SOM-DB5800 with the SOM-6867 installed. This is very similar to conga-qeval20-qa3-e3845 in that there is a reference carrier board (SOM-DB5800) with a Baytrail based SoM (SOM-6867) installed. Currently supported: - 2x UART (From ITE EC on SOM-6867) routed to COM3/4 connectors on SOM-DB5800. - 4x USB 2.0 (EHCI) - Video - SATA - Ethernet - PCIe - Realtek ALC892 HD Audio Pad configuration for HDA_RSTB, HDA_SYNC, HDA_CLK, HDA_SDO HDA_SDI0 is set in DT to enable HD Audio codec. Pin defaults for codec pin complexs are not changed. Not supported: - Winbond Super I/O (Must be disabled with jumpers on SOM-DB8500) - USB 3.0 (XHCI) - TPM Signed-off-by: George McCollister <george.mccollister@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
