From 2071f149e5d9376d392281689cf41cd165f7e19c Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 17 Dec 2015 17:47:41 +0900 Subject: ARM: uniphier: add functions to get SoC model/revision We sometimes have to implement different code depending on the SoC revision. This commit adds functions to get the model/revision number. Note: Model number: incremented on major changes of the SoC Revision number: incremented on minor changes of the SoC The "Model 2" exists for PH1-sLD3, ProXstream2/PH1-LD6b.
