Bear in mind that I'm almost at the point of not boot-testing anything
I sent to Linus because of the uselessness of the SDP4430 board now
that it's DT only - the only platform which boot-tests anything I send
is the 3430LDP board now.  If people care about that, maybe they can
assist with sorting out the issues I've raised on these lists about
the SDP4430 - and why the SDP4430 build remains disabled in my build
and boot system.

Looking at the boot log, it just stops after uboot hands over control.
With the lack of output from the decompressor, it's not possible to
tell whether it's a decompressor problem or a kernel problem.

I think you need to turn on the LL_DEBUG option, select the appropriate
output option, and also get the decompressor to use the kernel's debug
io functions to output it's stuff (I think the option is DEBUG_UNCOMPRESS).
