Reading more about executing the kernel directly from FLASH I've seen
that this can be done if the kernel is built for XIP (eXecute In Place).
Some documentation say that the Kernel is always XIP.  Is that true?

For applications to run directly from flash however the compiler must be
capable of generating Position Independent Code(PIC) and capable fo
generating the PIC form of flat executable.

Does the current version of mb-gcc support PIC?

Thanks in advance,
Vincent
