Hi Stefano,
Thanks for trying the patches out.

Argh, I'm seeing the same behavior with the latest mkimage source too.
It looks like there was a regression in the mkimage utility - the "-T"
option shouldn't be necessary to create a FIT image. I'll send a patch
to U-Boot to fix this behavior.

I did my testing using the dtc in the linux kernel source
(scripts/dtc/dtc, version 1.2.0) and version 1.2.0-rc1. I see the same
error as you when using version 1.2.0-g0ef21055.

Applying the following change should resolve the dtc syntax error.
diff --git a/scripts/mkits.sh b/scripts/mkits.sh
index 88411dd..75edc27 100755
--- a/scripts/mkits.sh

I'll wait a few more days for feedback then resubmit with the dts syntax
fix
Thanks for testing,
Peter
