Subject: [PATCH v2 10/11] fpga: Add flag to indicate bitstream needs decompression
Date: Wed, 14 Jun 2017 10:36:34 -0500 [thread overview]
Message-ID: <20170614153635.2763-11-atull@kernel.org> (raw)
In-Reply-To: <20170614153635.2763-1-atull@kernel.org>
From: Anatolij Gustschin <agust@denx.de>
Add a flag that is passed to the write_init() callback, indicating
that the bitstream is compressed.
The low-level driver will deal with the flag, or return an error,
if compressed bitstreams are not supported.
