The Z-Turn board is a low cost development board based on the Xilinx Zynq SoC. While it's powerful and quite versatile, it so far lacked upstream support. This patch adds basic support for the Z-Turn. It does however for now miss enablement for MIO51 reset which means that USB and ethernet don't work. For that either FSBL or SPL need to be adjusted. The SPL part will follow later. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
