================================================================
Wolfgang,

Thank you for responding. I suspected the CFI should work. Now all I
have to do is figure out what's wrong with my configuration, which is
shown below:

        #define CFG_FLASH_CFI 1        /* flash is CFI conformant */
        #define CFG_FLASH_CFI_DRIVER 1 /* use the common CFI driver */
        #define CFG_FLASH_EMPTY_INFO   /* print 'E' for empty sector on flinfo */
        
        
        #define CFG_FLASH_BASE    0xff000000
        #define CFG_MAX_FLASH_BANKS 1          /* max num of memory banks  */
        #define CFG_MAX_FLASH_SECT  142        /* max num of sects on one chip */
        #define CFG_FLASH_SIZE     0x01000000  /* 16 MByte */
        #define CFG_FLASH_ERASE_TOUT  8000     /* Timeout for Flash Erase (in ms)    */
        #define CFG_FLASH_WRITE_TOUT  5        /* Timeout for Flash Write (in ms)    */
        #define CFG_FLASH_LOCK_TOUT 5          /* Timeout for Flash Set Lock Bit (in ms) */
        #define CFG_FLASH_UNLOCK_TOUT 10000    /* Timeout for Flash Clear Lock Bits (in ms) */
        #define CFG_FLASH_PROTECTION           /* "Real" (hardware) sectors protection */



When I enable debug in the drivers directory by setting

    CFLAGS += -DET_DEBUG -DDEBUG

in drivers/Makefile, I see the following as u-boot-1.2.0 starts up:
