mb/kontron: Add Kontron mAL10 COMe module support
This patch adds support for the Kontron mAL10 COMe module with the
Apollo Lake SoC together with Kontron T10-TNI carrierboard.
Working:
- UART console and I2C on Kontron kempld;
- USB2/3
- Ethernet controller
- eMMC
- SATA
- PCIe ports
- IGD/DP
- SMBus
- HWM
Not tested:
- IGD/LVDS
- SDIO
TODO:
- HDA (codec IDT 92HD73C1X5, currently disabled)
Tested payloads:
- SeaBIOS
- Tianocore, UEFIPayload - without video, EFI-shell in console only
Tested on COMe module with Intel Atom x5-E3940 processor (4 Core,
1.6/1.8GHz, 9.5W TDP). Xubuntu 18.04.2 was used as a bootable OS
(5.0.0-32-generic linux kernel)
