According to correspondence I have had with fsl community the fsl-image-mfgtool-initramfs is not available for the warp7 board ( imx7s-warp ). If bitbaking fsl-image-mfgtool-initramfs with Krogoth it produces the following error:

The same command for the imx7dsabresd works. So, Has any one updated the recipe for the imx7s-warp or can someone give me some pointers based on the imx7dsabresd how too?
