2017-03-17FPGA: Add TS-7300 FPGA managerFlorian Fainelli1-0/+156
Add support for loading bitstreams on the Altera Cyclone II FPGA populated on the TS-7300 board. This is done through the configuration and data registers offered through a memory interface between the EP93xx SoC and the FPGA via an intermediate CPLD device. The EP93xx SoC on the TS-7300 does not have direct means of configuring the on-board FPGA other than by using the special memory mapped interface to the CPLD. No other entity on the system can control the FPGA bitstream.
