From ea65c98050f0f13f933119e1d073c8a138481ee4 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 18 Mar 2016 16:41:43 +0900 Subject: ARM: uniphier: drop PH1- prefix from CONFIG options and file names The current CONFIG names like "CONFIG_ARCH_UNIPHIER_PH1_PRO4" is too long. It would not hurt to drop "PH1_" because "UNIPHIER_" already well specifies the SoC family. Also, rename files for consistency.
