Subject: [PATCH 2/4] fpga: Add flag to indicate bitstream needs decrypting
Date: Mon, 27 Feb 2017 09:19:00 -0600 [thread overview]
Message-ID: <20170227151902.3403-3-atull@kernel.org> (raw)
In-Reply-To: <20170227151902.3403-1-atull@kernel.org>
From: Moritz Fischer <mdf@kernel.org>
Add a flag that is passed to the write_init() callback, indicating
that the bitstream is encrypted.
The low-level driver will deal with the flag, or return an error,
if encrypted bitstreams are not supported.
