I don;t know what exactly you are doing here, but you definitely have
a serious problem here.  Can you try and build the kernel with a
simple, known to be workign kernel configuration without any such
fancy features enabled?

Note that these "INFO:" messages are note printed by U-Boot, but by
Linux kernel code (arch/powerpc/boot/wrapper) which should not be
there at all for a plain Linux kernel image.  So your problem appears
not to be in U-Boot land, but somewhere in how you configure and build
the Linux kernel, probably as a result of enabling non-trivial kernel

My recommendation is realy to get rid of all such fancy stuff and get
a plain stupid Linux kernel image working first (i.e. without any of
this wrapper stuff) before to venture out into such areas.

Best regards,
