It is possible to build images entirely with OpenEmbedded tha twill boot
on a zedboard. We have sample ps7 files checked in (as mentioned when
you have a real fpga image you may need to change them). The script here:

https://github.com/balister/meta-sdr/blob/master/contrib/scripts/build-all.sh

Is what I have used to make test images. I do need to re-test against a
recent master though :)

Please keep in mind that the fsbl contains the ps7_init.c, what initializes most of the Zynq (MIO, Clocks, PLL's, ...). Use bootgen to build your own boot.bin comprising fsbl, bitstream (build by vivado) and u-boot.elf (build by bitbake).

I had an issue with a recipe downloading  source initially and now have a successful core-image-minimal build.  Initially I am trying to boot directly from the SD card and the boot process appears to hang up when reading the kernel.
