The FMC2 functional block makes the interface with: synchronous and
asynchronous static devices (such as PSNOR, PSRAM or other memory-mapped
peripherals) and NAND flash memories.
Its main purposes are:
  - to translate AXI transactions into the appropriate external device
  - to meet the access time requirements of the external devices
All external devices share the addresses, data and control signals with the
controller. Each external device is accessed by means of a unique Chip
Select. The FMC2 performs only one access at a time to an external device.
