I'm following the intructions in http://www.wiki.xilinx.com/Build+Device+Tree+Blob to generate the dts file for my hardware.
It's mostly based on the Zedboard but I've increased the DDR memory size, added a 256M NAND flash and remove the QPSI flash.
When creating the device-tree BSP I get the following
13:22:48 **** Build of project device_tree_bsp_0 ****
make -k all
make: *** No rule to make target 'all'.
