what is mirror flash?

when i use overlayRAM for calibration(MPC5744P). I have a problem.

I remap RAM area(0x4005C000) to mirror flash(0x08F98000), i can change mirror flash data by changing data in 0x4005C000(data in 0x00F98000 will not change), but after i power down mpc5744p, then power up mpc5744p, mirror flash data become the same as data in 0x00F98000, does that mean mirror flash data can't be reserved after power down?
