System Memory Layout

[Nguyen Manh Dung (G7)]

Hi all !
I'm building Embedded Linux System.
My board has 16M of RAM and 8M of Flash.The RAM is mapped from address 0x0000000 to address 0x00FFFFFF, and the flash is mapped from address 0x40000000 to address 0x407FFFFF
I use u-boot, kernel 2.6.12.5, JFFS2 root filesystem for my board.

can you help me :
1. How to layout system memory?
2. how to store u-boot image, Kernel image, root filesystem in flash.

thanks!
