[U-Boot] [PATCH] 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

- 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

The UARTs are provided by an LPC connected ITE branded EC. I forget which exact model (it's under the heatspreader and I'd rather not disassemble it at the moment). It had no publicly available datasheet, I might have been able to get it if I contacted ITE and signed an NDA.
and the comment says the one on the EC? Does that mean the UART on the EC comes out of reset as enabled and no software programming is needed (to turn it on, and set its IRQ to IRQ4)?
Correct, the first UART on the EC comes out of reset as enabled set the IRQ4. The second UART on the EC comes out of reset as enabled set to IRQ3. Standard PC COM1 and COM2.

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:
