d54123d293 boards/zynq: use genimage to generate a bootable SD card image
[Run-time tested on ZedBoard, build-tested on the other boards]
[Peter: also add host-dosfstools / host-mtools to make vfat images]

6465e4d34a 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]

3907b1ac66 zynq: document how to use custom ps7_init files
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
b9cd72cdbf ("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.

47b6b382b3 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.
