Subject: [PATCH 1/3] firmware: zynqmp-fpga: initialize flags at function start
Date: Wed, 18 Aug 2021 15:35:03 +0200	[thread overview]
Message-ID: <20210818133505.582698-2-m.tretter@pengutronix.de> (raw)
In-Reply-To: <20210818133505.582698-1-m.tretter@pengutronix.de>

The ZYNQMP_FPGA_BIT_ONLY_BIN flag is always set when programming the
FPGA. Simplify the code by initializing the flags with
ZYNQMP_FPGA_BIT_ONLY_BIN already set.
