1. When the FSMC is remapped at address 0x0000 0000, only the first two regions of Bank 1 memory controller (Bank1
NOR/PSRAM 1 and NOR/PSRAM 2) can be remapped. In remap mode, the CPU can access the external memory via
ICode bus instead of System bus which boosts up the performance.
2. Even when aliased in the boot memory space, the related memory is still accessible at its original memory space.
