From: Steffen Trumtrar <s.trumt...@pengutronix.de>
firmwareload can only load a bitstream into an FPGA without any
knowledge of possible additional needs (e.g. FPGA bridges).
These are defined in the fpga-region nodes in the devicetree. The
fpga-region describes the layout of the FPGA and the bridges it needs
en/disabled.
Add an option to let firmwareload go via the oftree route and load the
firmware that way.
