[PATCH 11/13] commands: firmwareload: allow loading firmware from dt

[Steffen Trumtrar]

From: Steffen Trumtrar <s.trumtrar at 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.
