Hi Sascha, we have tried as you suggested and it doesn't work without 

We found two things:

1.) There is early code which is not relocatable.

We solved this by adding -fPIC to the CPPFLAGS.
But I think, this is also solved with your patch

2.) The TEXTBASE is passed to the signGP tool, which is wrong if
       TEXT_BASE is different from the executing address before relocating.
       In our case TEXT_BASE would be 0x86000000 but the MLO is executed 

in internal SRAM at 0x40300000.

So I would suggest to create a config option like OMAP_IFT_BASE which 
can be passed to the signGP tool and is set to 0x40300000 per default..

What do you think?
