From ee8ef5afa87bf37d493bf7be9d475e54d6c2ebee Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 21 Jan 2017 18:05:27 +0900 Subject: ARM: uniphier: add macro to generate SoC data look-up function There are similar functions that look up SoC data by the SoC ID. The new macro UNIPHIER_DEFINE_SOCDATA_FUNC will be helpful to avoid the code duplication.
