[U-Boot] [PATCH 4/4] imx: cx9020: use distro boot

[linux-kernel-dev at beckhoff.com]

From: Steffen Dirkwinkel <s.dirkwinkel at beckhoff.com>

We switch from custom boot commands relying on uEnv.txt to distro boot.
This removes the automatic fpga bitstream loading in favor of loading
bitstreams via custom bootscripts (boot.scr) or after booting the
kernel.

Is this expected? I can't see what's wrong though i may have missed
something obvious.
