[U-Boot] [PATCH 3/3] zynq: Add Z-Turn board

Mon Jul 3 11:41:36 UTC 2017
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.
