Thanks!

Yes, I am on the documentation.
As we lack DRAM initialization at the moment, I use a tool to assemble
all the firmware bits together with boot0 into an image.
This should supersede Alex' pine64_image tool.
Shall this tool (written in C) also be part of U-Boot, say in the tools
directory? Or is this better pushed into the sunxi-tools repository?
Eventually with a proper SPL we will not need it anymore, so I refrained
from pushing it into U-Boot for now.

Cheers,
Andre.
