From 3b6e3898c2c68fa8340794c8abf5d47859069f98 Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Fri, 3 Jun 2016 18:41:35 +0530 Subject: 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.
