Sudhakar:

As I _*PREVIOUSLY*_explained to you off list, 
with the Toshiba app note, you need only

add CFG_CMD_IDE to your CONFIG_COMMANDS

and its associated parameters (this uses cmd_ide.c)

for example:

#define CFG_ATA_BASE_ADDR	0xF0000000
#define CFG_ATA_IDE0_OFFSET	0x0000
#define CFG_ATA_DATA_OFFSET	0x0000	 /* Offset for data I/O */
#define CFG_ATA_REG_OFFSET	0x0000	 /* Offset for normal register accesses*
#define CFG_ATA_STRIDE          2        /* Directly connected CF, needs a stride */

The above values MUST be adapted for your platform.
If you have the CF connected correctly it just works.


Please, READ the code, it exists, and works.
