Dan Carpenter	96bc818397	ARM: socfpga: checking the wrong variable ... This is a cut and paste bug. We had intended to check "sysmgr".

Alan Tull	e5f8efa5c8	ARM: socfpga: fpga bridge driver support ... Supports Altera SOCFPGA bridges: * fpga2sdram * fpga2hps * hps2fpga * lwhps2fpga Allows enabling/disabling the bridges through the FPGA Bridge Framework API functions. The fpga2sdram driver only supports enabling and disabling of the ports that been configured early on. This is due to a hardware limitation where the read, write, and command ports on the fpga2sdram bridge can only be reconfigured while there are no transactions to the sdram, i.e. when running out of OCRAM before the kernel boots. Device tree property 'init-val' configures the driver to enable or disable the bridge during probe. If the property does not exist, the driver will leave the bridge in its current state.
