Subject: [RFC PATCH 2/4] fpga: Add new properties to support user-key encrypted bitstream loading
Date: Tue, 4 May 2021 15:52:25 +0530 [thread overview]
Message-ID: <20210504102227.15475-3-nava.manne@xilinx.com> (raw)
In-Reply-To: <20210504102227.15475-1-nava.manne@xilinx.com>
This patch Adds ‘encrypted-key-name’ and
‘encrypted-user-key-fpga-config’ properties
to support user-key encrypted bitstream loading
use case.
