*** RAMFUNCS WARNING **
If you execute from NOR FLASH, RAM functions will be enabled. The
RAM functions will be positioned in SRAM in the same location as the
ISRAM heap and, as a result, those RAM functions will be destroyed
after the heap is initialized. That is not a problem now since
these RAM functions are only used in the early boot phase. If,
however, you should wish to preserve the RAM functions, then you
should also disable SAMA5_ISRAM_HEAP so that the RAM functions are
preserved beyond the boot phase.
