+ * ff000000 -> ff00ffff : IMAP       internal in the cpu
+ * 30000000 -> 300fffff : flash      connected to CS0
+ * 00000000 -> nnnnnnnn : sdram      setup by U-Boot
+ *
+ * CS pins are connected as follows:

+ * CS0 -512Kb boot flash
+ * CS1 - SDRAM #1
+ * CS2 - SDRAM #2
+ * CS3 - Flash #1
+ * CS4 - Flash #2
+ * CS5 - Lon (if present)
