Follow i.MX, Sunxi, RISC-V and Rockchip to generate u-boot.itb which includes U-Boot proper, ATF and DTBs in FIT format. ZynqMP supports FIT for quite a long time but with using out of tree solution. The patch is filling this gap. Tested on zcu102, zcu104 and zcu100/Ultra96. zcu100/Ultra96 v2.2 ATF build by: make DEBUG=0 ZYNQMP_CONSOLE=cadence1 RESET_TO_BL31=1 PLAT=zynqmp bl31 Signed-off-by: Michal Simek <michal.simek@xilinx.com>
