[U-Boot-Users] Suggestion on flash init

[Nuno João (Ext_NBS)]

	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
