How to add u boot to firmware image for  flash directly into memory?

I'm not sure I understand what you want to achieve. Can you explain in more detail?

The standard OpenWRT build process yields in a set of image files, and this set depends entirely on the selected target and subtarget. Some target/subtarget combinations will yield a U-boot image that can be written to the non-volatile memory chip, and some might yield an additional U-boot image that can be downloaded directly to the volative RAM memory of the device. Other combinations may not produce U-boot images at all, if the kernel & rootfs images intended for that target are directly compatible with the existing U-boot present on the device.

The discussion might have continued from here.
