boards/zynq: rename the DTB to be loaded by U-Boot
We are about to introduce genimage support for the Zynq boards. For all of them U-Boot loads the DTB from a file named "devicetree.dtb" so we need to rename it on the SD card image. We could use genimage itself to rename files while creating the image. But this would require a different genimage.cfg for each board, leading to duplicate code. Instead let's create a "devicetree.dtb" symlink pointing to the dtb listed in the configuration. Currently all the Zynq-based boards have only one DTS configured, but if one had two or more of them, the symlink would point to the first one. [Peter: only create symlink if dtb option is available] Signed-off-by: Luca Ceresoli <luca@lucaceresoli.net> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
