From 0fcd37172f22a55fecd5ae6752fc18218b88a8f3 Mon Sep 17 00:00:00 2001 From: Maxim Polyakov Date: Sat, 20 Jun 2020 17:26:21 +0300 Subject: 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).
