So I can boot using the steps you mentioned above.

But shouldnt the same bif work with bootgen?

however when I boot and inspect the processor state, xsdb returns "APU
L2 cache is held in reset"

Since the functionality to support RSA authentication is missing from
mkimage (I'll have to add that), I would first like to see it
functional with SPL using bootgen.

However the same bif doesnt even boot - is this to be expected?

also the layouts generated from the bif using mkimage and bootgen are
completely different (it seems that naively I expected them to be the
same); is there any information on the different layouts used for the
bootrom? 

thanks
