Subject: [PATCH v2 1/3] fpga: Add flag to indicate bitstream needs decrypting
Date: Mon, 20 Feb 2017 12:55:21 -0800
Message-ID: <1487624123-13579-1-git-send-email-mdf@kernel.org> (raw)

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.
