Subject: [PATCH v4 08/10] commands: firmwareload: allow loading firmware from dt
Date: Wed, 16 Jun 2021 08:32:44 +0200
Message-ID: <20210616063246.14900-8-s.trumtrar@pengutronix.de> (raw)
In-Reply-To: <20210616063246.14900-1-s.trumtrar@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.

v2->v3 - remove unused arg 'o'
       - use xstrdup()
