From 2c3f9261c80e8171ba813f8baef958c1edac3f0d Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Mon, 28 May 2018 15:27:43 +0300 Subject: ARC: Add support for EM Development Kit board Synopsys DesignWare ARC EM Development Kit (ARC EMDK) is an FPGA-based development platform from Synopsys aimed to speed-up development of software for ARC EM cores and entire subsystems based on ARC EM like Data Fusion, Secure and Sensor & Control subsystems. U-Boot is supposed to be used as a primary bootloader on EMDK allowing users to easily load and start their application from micro-SD card.
