/*
* The on-chip SRAM is split in two parts:
*    1) 128Kb of program memory located at 0x0000:0000
*    2) 128Kb of data memory beginning at the address 0x2000:0000
*
* The cortex-m7 can also use the main memory (DDR, shared with the Cortex-A53) and we choose to use it here for the program memory to overcome the size limitation.
