boards/zynq: rename the DTB to be loaded by U-Boot

2017-12-11T21:35:12+00:00

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 Signed-off-by: Peter Korsgaard

zynq: document how to use custom ps7_init files

2016-10-09T20:45:58+00:00

Since U-Boot supported SPL for Zynq boards at v2014.04 release, it became much easier to build a system. At that time, however, users still needed to manually copy ps7_init.c/h to the U-Boot source tree to generate a working SPL image because ps7_init.c/h output from Xilinx tools are not compatible with GPL. Later, the license problem was solved when Xilinx tools became able to output the GPL-compatible variants (ps7_init_gpl.c/h) as well. U-Boot v2015.07 or later includes ps7_init_gpl.c/h for major Zynq boards so that users can build a boot image straight away. Now Buildroot supports 3 boards (Zedboard, MicroZed, ZC706) without any manual intervention. This is a good thing itself, but commit b9cd72cdbfe3 ("zynq_zc706: bump U-Boot to xilinx-v2016.2") entirely dropped the information about custom ps7_init files. This commit provides up-to-date guidance for how to customize the ps7_init files.

zynq: unify readme.txt for all Zynq boards

The readme.txt for the three boards are almost the same, so merge them into board/zynq/readme.txt. Signed-off-by: Masahiro Yamada Reviewed-by: Matt Weber Signed-off-by: Thomas Petazzoni
