From 4bb641f4d28053bd1ff4af73dc0a63be2151f851 Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Mon, 25 Apr 2016 14:37:33 +0530 Subject: [PATCH 15/93] armv8: ls1012a: Add support of ls1012ardb board QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance development platform, with a complete debugging environment. The LS1012ARDB board supports the QorIQ LS1012A processor and is optimized to support the high-bandwidth DDR3L memory and a full complement of high-speed SerDes ports.
