The bootstrap support did not play well with the PBL support.
And MULTI_IMAGE somehow forced this on me.

I did not dive deep into why bootstrap and MULTI_IMAGE did not work.
I looked at the binraty using objdump, and could see that without

Unless there are something I missed so PBL support should work I will
update the commit message for a v2 of the pathset.

Note: I also had to disable MMU support to get bootstrap working.
With MMU enable it halted when __mmu_cache_on() was called in
mmu-early.c
I will also try to look a little deeper into this, but here I have
only limited hope as my debugging is so far limited to
using pr_info(...).
