From a13110a99fffb431db60ec5b50e263d0bd2b811d Mon Sep 17 00:00:00 2001 From: Klaus Goger Date: Fri, 7 Apr 2017 19:13:38 +0200 Subject: rockchip: ARM64: split RK3399-Q7 board off the RK3399-EVB board The RK3399-Q7 SoM is a Qseven-compatible (70mm x 70mm, MXM-230 connector) system-on-module from Theobroma Systems, featuring the Rockchip RK3399. It provides the following feature set: * up to 4GB DDR3 * on-module SPI-NOR flash * on-module eMMC (with 8-bit interace) * SD card (on a baseboad) via edge connector * Gigabit Ethernet w/ on-module Micrel KSZ9031 GbE PHY * HDMI/eDP/MIPI displays * 2x MIPI-CSI * USB - 1x USB 3.0 dual-role (direct connection) - 2x USB 3.0 host + 1x USB 2.0 (on-module USB 3.0 hub) * on-module STM32 Cortex-M0 companion controller, implementing: - low-power RTC functionality (ISL1208 emulation) - fan controller (AMC6821 emulation) - USB<->CAN bridge controller Note that we use a multi-payload FIT image for booting and have Cortex-M0 payload in a separate subimage: we thus rely on the FIT image loader to put it into the SRAM region that ATF expects it in.
