Subject: [PATCH v6 1/2] fpga: Add flag to indicate bitstream needs decompression
Date: Fri,  9 Jun 2017 02:22:25 +0200	[thread overview]
Message-ID: <1496967746-12196-2-git-send-email-agust@denx.de> (raw)
In-Reply-To: <1496967746-12196-1-git-send-email-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.
