I am using the CFI driver (as it is in u-boot 1.1.3) with Spansion flash chips (S29GL512N11xxx: 2 x 16 bit chips, 32 bit port). I had no problems; I can do all the usual operations.

My config is:

#define CFG_FLASH_BASE CFG_FLASH_MEM_BASE

#define CFG_MAX_FLASH_BANKS 1 /* number of banks */ #define CFG_MAX_FLASH_SECT 512 /* sectors per device */ #undef CFG_FLASH_CHECKSUM #define CFG_FLASH_ERASE_TOUT 1024000 /* Flash Erase Timeout (ms) */ #define CFG_FLASH_WRITE_TOUT 500 /* Flash Write Timeout (ms) */

#define CFG_FLASH_CFI_DRIVER #define CFG_FLASH_CFI #define CFG_FLASH_EMPTY_INFO

Cheers

I have tested cfi_flash.c for a while. Unfortuanately, it fails for Spansion S29AL016M. The chip can be recognized, chip information is all correct, but the erase and write routines fail.
