Alignement issues, possibly, although we do align the location pointer 
before the overlay point -- or some bug in the linker.

Oh--I did not mean to forget the linker warning thing. Just separate the 
issues, because I think this particular linker warning is unrelated with 
getting the board working.

So Sanjeev would change the u8 to an int and proceed with board debug, 
and I would investigate this issue -- actually, try and find a minimal 
example that I could go to the binutils list with rather than a 
full-blown u-boot tree.

No change.
