Leo,
The flash wrapper is a controller. Think of it as some digital logic that is responsible for the interface between the CPU and the actual flash memory. It also has state machine to program the flash memory.

The mirrored flash image is mainly used for diagnostic. Normally the flash memory is mapped to starting address at 0x0 of the CPU's memory map. However, the flash memory is also mapped to 0x20000000 in the CPU's memory map.
