From 8afd4ea5b9d5d9a18db4e9fee16d89999711d205 Mon Sep 17 00:00:00 2001 From: Loic Devulder Date: Wed, 3 Oct 2018 12:02:07 +0200 Subject: [PATCH] ARM: meson: Add Khadas VIM2 board support This adds platform code for the Khadas VIM2 board based on a Meson GXM (S912) SoC with the Meson GXM configuration. This initial submission supports UART, MMC/SDCard and Ethernet. USB is partially supported. All the code is from Neil Armstrong! I just rebased the code, do some cleanup and tested on my board.
