Subject: cmd: zynqrsa: Added support to load bitstream
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=00186544d431ef499bea3d7127886b665f638b43;p=thirdparty%2Fu-boot.git

cmd: zynqrsa: Added support to load bitstream

This patch added support to check whether the bitstream is full
or none. On the basis of that, it loads the bitstream. Only
full bitstream loading is supported because we don't have a way
to identify it based on data in boot.bin format.
