From 33886693b645dd737a21065c095eac2ce7cbd956 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 17 Dec 2015 17:47:47 +0900 Subject: ARM: uniphier: merge umc/ and ddrphy/ into a single directory The UMC (Universal Memory Controller) and the DDR PHY block are highly related to each other. It is better to have both code in the same directory.
