Thanks very much. As I suspected it seems that I missed:
export WTP=/work/community/A3700-utils-marvell
before building ATF, so the ATF build system couldn't find the tools to
assemble the image. It looks like this should avoid my steps 4-6 and
indeed simplifies the process.

Thanks, that would be very nice.

Yeah, that was my plan for tonight as well, since this would allow me to
experiment safely with the generated image.

Oh, BTW: Chain-loading mainline U-Boot worked quite nicely and I could
launch the generic debian-testing installer via EFI boot. The only issue
was that I was using the U-Boot DT directly, which isn't enough for the
kernel (missing clocks and interrupts). I will try to send some patches
to bring the U-Boot DT in sync with the kernel one. If this is in place,
one could simply attach some (UEFI enabled) USB pen drive and it should
start without further ado (given a newer U-Boot in the SPI flash with
EFI support).

Thanks again!

Cheers,
Andre.
