[PATCH] reset: socfpga: use arch_initcall for early initialization

2014-10-08 Thread dinguyen
From: Dinh Nguyen There are certain drivers that are required to get loaded very early using arch_initcall. An example of such a driver is the SOCFPGA's FPGA bridge driver. This driver has to get loaded early because it needs to enable FPGA components that are connected to the bridge. This FPGA
