Hi,

I have tested your patches against last mkimage utility provided with
u-boot. The utility requires to pass the type of the image (flat_dt),
even if this is not mentioned in the help output. Without the image type
parameter, no image is generated, and no error is reported.
It should be:

    ${MKIMAGE} -f "$object/uImage.its" - T flat_dt "$ofile"

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 have tried to get an image for the lite5200b board, because I have the
possibility to test the result on the target. However, dtc fails to
compile the its generated by your script (Version: DTC 1.2.0-g0ef21055,
cloned from jdt).

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.

DTC: dts->dtb  on file "arch/powerpc/boot/uImage.its"
Error: arch/powerpc/boot/uImage.its 1:0 syntax error

Do you test in different conditions ?

Applying the following change should resolve the dtc syntax error.

diff --git a/scripts/mkits.sh b/scripts/mkits.sh

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

Thanks for testing,
Peter
