I want to make the Beagle board (with u-boot) to look like a USB Mass Storage Device when it is connected to the host PC. Can anyone suggest regarding the files that I need to update in u-boot code, to make the Beagle board look like a USB Mass Storage Device.
You don't need to and should not change anything in U-Boot. All it takes to do what you want is a two stage boot procedure. In the first step, boot Linux.
Keep in mind that U-Boot is a boot loader, not an operating system. Fancy stuff should be done where the enviornment is available for it, i. e. in an operating system.
[Note: even if you implement Device Mode support as an USB Mass Storage Device in U-Boot that would be just the first step - you would then most probably need write support for the file system(s) of your choice, and ... and ...]
