I have tested and it works! Kernel version Letux-4.10.4 already includes
a patch.

I can also flash the kernel and rootfs from user-space and the GTA04A4
can boot to LXDE from NAND.

There are only two remaining issues for perfection:
a) U-Boot complains a lot about a missing MMC and adds 20 seconds to boot time
b) our Letux LXDE is still too big for NAND...

Anyways this is already good for finalizing the last GTA04A5 boards (i.e.
flashing OneNAND...).

What I have also added is an entry for /etc/init.d to shut down the
Modem at "poweroff"/"halt". This would have been an issue since sometimes
you ma forget too shut it down actively and do a poweroff. And one day
later the battery is empty although the Linux was powered off...
