Hmm, I don't know the SAM9G45, but reading the linux stuff, the UART code
should be the same, maybe the way to retrieve the amount of memory changed,
and at91_ramsize() is wrong for your CPU, you can test it quickly by 
hardcoding the ram size in at91_ramsize(), or maybe there's some new stuff to
enable the DBGU port ?
