NOTE: MM_REGIONS must also be set to indicate the total number of
memory regions to be added to the heap.

*** DO NOT SELECT THIS OPTION IF YOU ARE EXECUTING FROM INTERNAL SRAM!! **
In this case, the remaining ISRAM will automatically be added to the
heap (using RAM_END).
*** 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.
