Bit-banding in SRAM region (Cortex-M4)

Hi.

I would like to use bit-banding feature in SRAM, but don't know exactly how to implement it with C. I already use bit-banding in peripheral region with this kind of macro:

#define BITBAND_PERI_REF        0x40000000

#define BITBAND_PERI_BASE     0x42000000

#define BITBAND_PERI(a,b)         ((BITBAND_PERI_BASE + (a - BITBAND_PERI_REF) * 32 + (b * 4)))

But I am confused how to connect bit-banding with some random word (half-word or byte) in SRAM, where separate bits could represent some statuses.

Thank you for your help.
