Bit banding SRAM when booting from SRAM?

Does the bit band alias base address for the SRAM (0x22000000) change to 0x02000000 if I select to boot from system memory block (SRAM)?

I have read that the SRAM will appear at 0x00000000 if embedded SRAM is selected as boot space.

No, it doesn't. The bit-band is fixed at 0x22000000 and 0x42000000. If the memory is remapped to 0x0 by the memory system, the processor will not carry out bit-band operation to it.
