Yes, I can now reproduce with "all" and gcc 6.3.0. And even with letux_ci20_defconfig.

So likely we have disabled/deconfigured something which is needed for "all" to build "its"/"itb".

arch/mips//boot/compressed/Makefile tells that this is Flattened Image Tree (.itb) image.

Here I found a good description what it is:


But to be honest, I do not see any benefits for the Letux projects...

Except for the fw_getenv() issue, the U-Boot can be stable for years.
So there is no need to pack it together with kernel images which change
every week.

And for ARM we have a single uImage for all. Multiplying this with the
number of boards (each having a different U-Boot setup) we support, would
just add a lot of bytes to the download server.

Back to "all": I have not (yet?) found a way to disable this feature during
kernel build. Or a clear reason why it fails. Maybe, because we do NOT have
an initrd?
