+Flashing the images to NAND
+===========================
+The AIS image can be written to NAND using the u-boot "nand"
+commands.
+
+Example:
+
+The OMAPL138_LCDK requires the AIS image to be written to block 1 of
+the NAND flash.
+
+ 1 - Find out the block size using "nand info"
+ 2 - Download the AIS image to memory
+ 3 - Write the AIS image form memory to the first block
+
+In the case of the LCDK:
+  U-Boot > nand info
+      Erase size    131072 b (0x20000)
+  U-Boot > tftp u-boot.ais
+      Load address: 0xc0700000
+      Bytes transferred = 477448 (74908 hex)
+  U-Boot > nand write 0xc0700000 0x20000 0x75000

 Flashing the images to MMC
 ==========================
 If the boot pins are set to boot from mmc, the RBL will try to load the
