[meta-xilinx] [PATCH 08/12] zc702-zynq7: Switch over to in kernel device tree

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


* Switch to the device tree that is available in the kernel source tree
* Remove the in layer device tree and configuration for the in layer
  device tree
* Setup IMAGE_BOOT_FILES with the correct target device tree from the
  kernel source/recipe
* Setup U-Boot uEnv.txt to use the correct target device tree
