-have been configured correctly for the board. As a time saving measure we
-load MLO into memory in one location, copy it into the three locatations
-that the ROM checks for additional valid copies, then load U-Boot into
-memory. We then write that whole section of memory to NAND.

+have been configured correctly for the board. All images are first loaded
+into memory, then written to NAND.
+
+Step-1: Building u-boot for NAND boot
+ Set following CONFIGxx options for NAND device.
+ CONFIG_SYS_NAND_PAGE_SIZE number of main bytes in NAND page
+ CONFIG_SYS_NAND_OOBSIZE number of OOB bytes in NAND page
+ CONFIG_SYS_NAND_BLOCK_SIZE number of bytes in NAND erase-block
+ CONFIG_SYS_NAND_ECCPOS ECC map for NAND page
+ CONFIG_NAND_OMAP_ECCSCHEME (refer doc/README.nand)
+
+Step-2: Flashing NAND via MMC/SD
+ # select BOOTSEL to MMC/SD boot and boot from MMC/SD card
+ U-Boot # mmc rescan
+ # erase flash
+ U-Boot # nand erase.chip
+ U-Boot # env default -f -a
+ U-Boot # saveenv
+ # flash MLO. Redundant copies of MLO are kept for failsafe
+ U-Boot # load mmc 0 0x82000000 MLO
+ U-Boot # nand write 0x82000000 0x00000 0x20000
+ U-Boot # nand write 0x82000000 0x20000 0x20000
+ U-Boot # nand write 0x82000000 0x40000 0x20000
+ U-Boot # nand write 0x82000000 0x60000 0x20000
+ # flash u-boot.img
+ U-Boot # load mmc 0 0x82000000 u-boot.img
+ U-Boot # nand write 0x82000000 0x80000 0x60000
+ # flash kernel image
+ U-Boot # load mmc 0 0x82000000 uImage
+ U-Boot # nand write 0x82000000 ${nandsrcaddr} ${nandimgsize}
+ # flash filesystem image
+ U-Boot # load mmc 0 0x82000000 filesystem.img
+ U-Boot # nand write 0x82000000 ${loadaddress} 0x300000
+
+Step-3: Set BOOTSEL pin to select NAND boot, and POR the device.
+ The device should boot from images flashed on NAND device.
