> 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.
