///@section	Intro Introduction
///
///		Mx2 Linux NAND Flash System include BootLoader, MTD

///
///@subsection	@PBAXD Program NAND With Multi-ICE
///
///		-# Untgz the FlashNAND.tgz into your local directory, for example "D:\FlashNAND".
///		-# Set boot[0:3] as all on.
///		-# Loader NAND Flash Program "D:\FlashNAND\Program Template v0.3 NFC ECC\Project\ProjectTemplate_NFC.mcp" with AXD.
///		-# Click "Run" button, and the program will break at main function.
///		-# Axd Menu file->load memory from file.
///		-# Load bootloader.bin to 0xC3000000.
///		-# Press F5 to run program until exit.
///		-# Boot Switch as OFF-OFF-OFF-ON.
///		-# Reboot.
///		-# Press any key when you see "Press Any Key...".
///		-# Choose your option.
///		-# Plug USB Cable.
///		-# If you are first using this, win2k will install driver for you. Wait until win2k install driver finished.
///		-# You can see a "movable driver" in your computer.
///		-# Copy your image file to this driver(only one file, NOT delete file in this driver).
///		-# Right-click the driver's icon and click "eject" command.
///		-# Your can see a serial "." which indicates the process of programming.
///		-# Reboot if seeing "Press Reset button on ADS Board".
///		-# Repeat step 9 to 18 to update the bootloader, kernel and rootdisk. 
///
///@remarks	You must have multi-ice,Arm Axd,USB Cable. Your OS Must be win2k or above.

///@section	NPInfo NAND Partition Info
///		-# 0000 0000-0000 3FFF Bootloader(16K)\n
///		   First section:  0000 0000-0000 0800  ipl(you can @b only use first 1.5K,@b not 2K)\n
///		   Second section: 0000 0800-0000 3FFF  spl(14K)\n
///		-# 0010 0000-002F FFFF Kernel(2M)\n
///		-# 0030 0000-01FF FFFF Root Disk(29M, when large then 32M,jffs2 have some problem)\n
///
///@section 	MKJFFS Howto Build JFFS/JFFS2 Image
///		For build JFFS/JFFS2 Image, you must download tools from redhat. mkfs.jffs2 or mkjffs\n
///		Base use way to mkfss.jffs2 is: \n
///		mkfs.jffs2 -d \<your rootdisk\> -e 16 -o rt.jffs2 
///@remarks	Erase size must be same to Flash erase size \n
///		In Mx21 ADS board:\n
///		NAND is 16k. \n
///		AMD flash is 128K. \n
