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.

Hi Greg,

Would it be helpful for us to resend patches for you to take with you
on cc?  Or is it enough that they are on lkml?

Thanks,
Alan Tull

Can I know the reason for this? I know that there were some discussion
in past. But just add them to your linux-fpga.git repo and send pull
request to Greg and proper time when he expects that.

Thanks,
Michal

Yes, please send patches with your signed-off-by: for what I should
take.

Does it make sense to have git repo in MAINTAINERS file then?

T:	git git://git.kernel.org/pub/scm/linux/kernel/git/atull/linux-fpga.git

Why not, that doesn't mean that's where they get pulled from, but
rather, where the latest version of the patches can be found at.
