 1. After applying the patch, ext4 specific commands can be seen
    in the boot loader prompt using
-        UBOOT #help
+       UBOOT #help
 
-        ext4load- load binary file from a Ext4 file system
-        ext4ls  - list files in a directory (default /)
-        ext4write- create a file in ext4 formatted partition
+       ext4load- load binary file from a Ext4 file system
+       ext4ls  - list files in a directory (default /)
+       ext4write- create a file in ext4 formatted partition
 
 2. To list the files in ext4 formatted partition, execute
-        ext4ls <interface> <dev[:part]> [directory]
-        For example:
-        UBOOT #ext4ls mmc 0:5 /usr/lib
+       ext4ls <interface> <dev[:part]> [directory]
+       For example:
+       UBOOT #ext4ls mmc 0:5 /usr/lib
 
 3. To read and load a file from an ext4 formatted partition to RAM, execute
-        ext4load <interface> <dev[:part]> [addr] [filename] [bytes]
-        For example:
-        UBOOT #ext4load mmc 2:2 0x30007fc0 uImage
+       ext4load <interface> <dev[:part]> [addr] [filename] [bytes]
+       For example:
+       UBOOT #ext4load mmc 2:2 0x30007fc0 uImage
 
 4. To write a file to a ext4 formatted partition.
-        a) First load a file to RAM at a particular address for example 0x30007fc0.
-        Now execute ext4write command
-        ext4write <interface> <dev[:part]> [filename] [Address] [sizebytes]
-        For example:
-        UBOOT #ext4write mmc 2:2 /boot/uImage 0x30007fc0 6183120
-        (here 6183120 is the size of the file to be written)
-        Note: Absolute path is required for the file to be written
