/* FSMC NAND memory address computation */
#define ADDR_1st_CYCLE(ADDR) (u8)((ADDR)& 0xFF) /* 1st addressing cycle */
#define ADDR_2nd_CYCLE(ADDR) (u8)(((ADDR)& 0x0F00) >> 8) /* 2nd addressing cycle */
#define ADDR_3rd_CYCLE(ADDR) (u8)(((ADDR)& 0xFF0000) >> 12) /* 3rd addressing cycle */
#define ADDR_4th_CYCLE(ADDR) (u8)(((ADDR)& 0xFF000000) >> 20) /* 4th addressing cycle */
