+		How to mount the root file system in uClinux/Blackfin
+		-----------------------------------------------------
+
+1	Mounting EXT3 File system.
+	------------------------
+
+	Creating an EXT3 File system for uClinux/Blackfin:
+
+
+Please follow the steps to form the EXT3 File system and mount the same as root
+file system.
+
+a	Make an ext3 file system as large as you want the final root file
+	system.
+
+		mkfs.ext3  /dev/ram0 <your-rootfs-size-in-1k-blocks>
+
+b	Mount this Empty file system on a free directory as:
+
+		mount -t ext3 /dev/ram0  ./test
+			where ./test is the empty directory.
+
+c	Copy your root fs directory that you have so carefully made over.
+
+		cp -af  /tmp/my_final_rootfs_files/* ./test
+
+		(For ex: cp -af uClinux-dist/romfs/* ./test)
+
+d	If you have done everything right till now you should be able to see
+	the required "root" dir's (that's etc, root, bin, lib, sbin...)
+
+e	Now unmount the file system
+
+		umount  ./test
+
+f	Create the root file system image.
+
+		dd if=/dev/ram0 bs=1k count=<your-rootfs-size-in-1k-blocks> \
+		> ext3fs.img
+
+
+Now you have to tell the kernel that will be mounting this file system as
+rootfs.
+So do a make menuconfig under kernel and select the Ext3 journaling file system
+support under File system --> submenu.
+
+
+2.	Mounting EXT2 File system.
+	-------------------------
+
+By default the ext2 file system image will be created if you invoke make from
+the top uClinux-dist directory.
+
+
+3.	Mounting CRAMFS File System
+	----------------------------
+
+To create a CRAMFS file system image execute the command
+
+	mkfs.cramfs ./test cramfs.img
+
+	where ./test is the target directory.
+
+
+4.	Mounting ROMFS File System
+	--------------------------
+
+To create a ROMFS file system image execute the command
+
+	genromfs -v -V "ROMdisk" -f romfs.img -d ./test
+
+	where ./test is the target directory
+
+
+5.	Mounting the JFFS2 Filesystem
+	-----------------------------
+
+To create a compressed JFFS filesystem (JFFS2), please execute the command
+
+	mkfs.jffs2 -d ./test -o jffs2.img
+
+	where ./test is the target directory.
+
+However, please make sure the following is in your kernel config.
+
+/*
+ * RAM/ROM/Flash chip drivers
+ */
+#define CONFIG_MTD_CFI 1
+#define CONFIG_MTD_ROM 1
+/*
+ * Mapping drivers for chip access
+ */
+#define CONFIG_MTD_COMPLEX_MAPPINGS 1
+#define CONFIG_MTD_BF533 1
+#undef CONFIG_MTD_UCLINUX
+
+Through the u-boot boot loader, use the jffs2.img in the corresponding
+partition made in linux-2.6.x/drivers/mtd/maps/bf533_flash.c.
+
+NOTE - 	Currently the Flash driver is available only for EZKIT. Watch out for a
+	STAMP driver soon.
+
+
+6. 	Mounting the NFS File system
+	-----------------------------
+
+	For mounting the NFS please do the following in the kernel config.
+
+	In Networking Support --> Networking options --> TCP/IP networking -->
+		IP: kernel level autoconfiguration
+
+	Enable BOOTP Support.
+
+	In Kernel hacking --> Compiled-in kernel boot parameter add the following
+
+		root=/dev/nfs rw ip=bootp
+
+	In File system --> Network File system, Enable
+
+		NFS file system support --> NFSv3 client support
+		Root File system on NFS
+
+	in uClibc menuconfig, do the following
+	In Networking Support
+		enable Remote Procedure Call (RPC) support
+			Full RPC Support
+
+	On the Host side, ensure that /etc/dhcpd.conf looks something like this
+
+		ddns-update-style ad-hoc;
+		allow bootp;
+		subnet 10.100.4.0 netmask 255.255.255.0 {
+		default-lease-time 122209600;
+		max-lease-time 31557600;
+		group {
+			host bf533 {
+				hardware ethernet 00:CF:52:49:C3:01;
+				fixed-address 10.100.4.50;
+				option root-path "/home/nfsmount";
+			}
+		}
+
+	ensure that /etc/exports looks something like this
+		/home/nfsmount *(rw,no_root_squash,no_all_squash)
+
+	 run the following commands as root (may differ depending on your
+	 distribution) :
+		-  service nfs start
+		-  service portmap start
+		-  service dhcpd start
+		-  /usr/sbin/exportfs
