Thank you for the quick response!

You are right - the uImage generated in the above step is not directly
used on boot (without flashing separately on typical PowerPCSPE boards).
I'm working on a solution for this, separately.

However, the powerpc specific option CONFIG_DEFAULT_UIMAGE always tries
to build uImage at (Debian package) linux build time, see
arch/powerpc/boot/Makefile:207:

image-$(CONFIG_DEFAULT_UIMAGE)          += uImage

So can we add u-boot-tools as build-dep for powerpcspe? Or do you have a
different suggestion for making the default package "linux" build?

Thanks in advance,

Roland
