From f4e190e317b860bb15e221a29cbf16976a04e3ca Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 28 Aug 2015 20:13:18 +0900 Subject: [PATCH] ARM: uniphier: enable SPL_OF_CONTROL Device Tree really improves code maintainability and is now available for SPL too. This is the state-of-the-art implementation in U-boot. The board files (platform data) are no longer needed.
