-	rootfs.cpio.gz.uboot -> uramdisk.image.gz
-	uImage -> uImage
-	boot.bin -> boot.bin
+The firmware releases for the Xilinx Zynq silicons depend on Xilinx some propietary tools or code. This dependency has been reduced to a pair of source files available in the regular Xilinx SDK.

+You will need this files from Xilinx tree to generate the later listed files:
+	ps7_init.c
