L4 Bootsrap Fiasco Addr

Hello All,

I am working on porting Fiasco.OC to openrisc (or1k), but are stucked at booting the kernel.
The problem is that the addr in boot_info.kernel_start is pointing to the beginning of the bootsrap, and therefore it will not start the kernel.
In startup.cc there is the mbi, mb_info and mb_mod, which I suppose is the place where the addr is coming from.
But where is it set exactly?

For or1k IMAGE_MODE is used.
The output of the bootstrapping is at the end.

Thanks a lot for the help,
Tobias
