We normally just call this genimage.cfg, so I've renamed this.

And dropped BOARD_NAME / OUTPUT_DIR.

exit $? isn't needed, so I've dropped that.

Zynq 7000 also has a FPU, so I've enabled BR2_ARM_ENABLE_VFP=y to use
it.

You didn't select 4.6.x kernel headers, so I've added that.

The genimage configuration uses dosfstools and mtools, so I've added
those host packages.

u-boot tools isn't needed by the post-image script, so I've removed
that.

Committed with these fixes, thanks.
