Subject: [PATCH 1/2] fpga: Add flag to indicate bitstream needs decrypting

From: Moritz Fischer <moritz.fischer@...us.com>

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.
