[meta-xilinx] [PATCH 07/12] picozed-zynq7: Rework device tree to use kernel source include

Nathan Rossi nathan at nathanrossi.com
Wed Feb 24 01:31:00 PST 2016


* Rework the picozed-zynq7.dts device tree to use the kernel source
  include 'zynq-7000.dtsi'
* Store the new device tree in the device-tree recipe directory
* Remove existing device tree from conf/machine/boards
