this is the patch and how to use it:

+#define CONFIG_DOS_PARTITION
+#define CFG_IDE_MAXBUS          1       /* max. 1 IDE bus               */
+#define CFG_IDE_MAXDEVICE       1       /* max. 2 drives per IDE bus    */
+
+#define CFG_ATA_IDE0_OFFSET     (0)
+
+#define CFG_ATA_BASE_ADDR       (0x10000000)
+
+/* Offset for data I/O                  */
+#define CFG_ATA_DATA_OFFSET     (0)
+
+/* Offset for normal register accesses  */
+#define CFG_ATA_REG_OFFSET      (0)
+
+/* Offset for alternate registers       */
+#define CFG_ATA_ALT_OFFSET      (0)
+
+/* Interval between 
registers                                                */
+#define CFG_ATA_STRIDE          (1<<21)
+#define __io
