Resolved! "Supertype" of uint8_t * and __IO uint8_t *?

This questions is mildly naive, but is there a way to define a function f() so that one parameter p accepts both uint8_t * and __IO uint8_t * arguments, i.e., function f() writes either to internal SRAM or external SDRAM depending on the pointer pass...
