Viresh KUMAR - Oct. 1, 2010, 11:56 a.m.
From: Vipin Kumar <vipin.kumar@st.com>

Until now, the platform code assumed 1 32 bit register to be used for pad
multiplexing. This assumption is not true for SPEAr13xx devices, so the generic
implementation of pad multiplexing adopts a new concepts of multiple
multiplexing registers.
