 This patch series adds support for ext4 ls,load and write features in uboot
 Journaling is supported for write feature.
 
+To enable support for the ext4 (and ext2) filesystem implementation,
+#define CONFIG_FS_EXT4
+
+If you want write support,
+#define CONFIG_EXT4_WRITE
+
 To Enable ext2 ls and load commands, modify the board specific config file with
 #define CONFIG_CMD_EXT2
+This automatically defines CONFIG_FS_EXT4 for you.
