From 0f4f0c8ff1da9171bca0dc01ce5551e8b6d2f0f3 Mon Sep 17 00:00:00 2001 From: Moritz Fischer Date: Mon, 27 Feb 2017 09:19:00 -0600 Subject: fpga: Add flag to indicate bitstream needs decrypting 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.
