See my comments on the patch itself.

You will be happy to know that in the most recent Vivado/XSDK 2014.3 tools (they were released today) changes have been made to the generation of the files.

The generated ps7_init.c/h are licensed under the same license that the FSBL source is released under in the Xilinx/embbeddedsw repo on github. Technically this is a non-free license, due to it requiring use of the software to be used only with Xilinx devices or in interaction with Xilinx devices.

Also generated are ps7_init_gpl.c/h, these are the same as the ps7_init.c/h except with a GPL license (specifically GPLv2+, so it is compatible with U-Boot). So you can now build a fully GPL compliant U-Boot SPL for you board :).

Nathan
