From 3f77fb40597994a5438d0cd1c5ddc6d564b567b9 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Tue, 26 Mar 2019 11:20:35 +0100 Subject: [PATCH] boards: Amlogic: Add support for Libretech-AC LibreTech AC is a single board computer manufactured by Libre Technology with the following specifications: - Amlogic S805X ARM Cortex-A53 quad-core SoC @ 1.2GHz - ARM Mali 450 GPU - 512MiB DDR4 SDRAM - 10/100 Ethernet - HDMI 2.0 4K/60Hz display - 40-pin GPIO header - 4 x USB 2.0 Host - eMMC, SPI NOR Flash - Infrared receiver The u-boot specific code is the same as the P212 support, so use the P212 board support code with a distinct defconfig and config include files.
