[U-Boot] [PATCH V5 2/3] SPEAr: Configure FSMC driver for NAND interface
Amit Virdi

Tue May 22 12:15:55 CEST 2012
From: Vipin KUMAR <vipin.kumar at st.com>
Since FSMC is a standard IP and it supports different memory interfaces, it
is supported independent of spear platform and spear is configured to use that
driver for interfacing with the NAND device
