Subject: [PATCH] firmware: zynqmp-fpga: do not load PL with ONLY_BIN flag unless necessary
Date: Sun,  1 May 2022 20:26:07 +0200	[thread overview]
Message-ID: <20220501182607.38125-1-matthias.fend@emfend.at> (raw)

Since pmu-fw release 2018.3, the ZYNQMP_FPGA_BIT_ONLY_BIN flag is no
longer used. This wasn't a problem for a while, but in newer versions a
validation sequence will fail if this flag is set. This means that the PL
can no longer be loaded.

Do not set the ZYNQMP_FPGA_BIT_ONLY_BIN flag unless absolutely necessary
to avoid this problem.
