Hello,

I did not know that u-boot can boot "naked" Linux kernels. I am
rather new to u-boot and all the documention I have read only
mentions booting uImages.  Neither the description of
u-boot-sunxi in the sunxi wiki nor the official u-boot manual at
www.denx.de makes any mention of the bootz command, just of bootm.
The same with fsload vs. ext2load.

I'll look if I find appropriate documentation and rework the boot
script.

Regards,
Karsten
