From: Masahiro Yamada Date: Fri, 28 Aug 2015 11:13:18 +0000 (+0900) Subject: ARM: uniphier: enable SPL_OF_CONTROL X-Git-Tag: v2015.10-rc3~47 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f4e190e317b860bb15e221a29cbf16976a04e3ca;p=platform%2Fkernel%2Fu-boot.git 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.
