From 7831c4b2a11b35cde9bc548b600ec047aac7f98f Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Thu, 15 May 2014 11:08:55 +0100 Subject: [PATCH 1/3] ARM: qcom: Enable ARM_AMBA option for Qualcomm SOCs. As some of the IPs on Qualcomm SOCs are based on ARM PrimeCell IPs. For example SDCC controller is PrimeCell MCI pl180. Adding this option will give flexibility to reuse the existing drivers as it is without major modifications.
