[U-Boot] can i pass an bootarg/environment variable from the command line while building u-boot?

Hi! Is there a way i can set my bootarg variable form the command line while building u-boot? We have implemented a two-stage u-boot process for our products. The main idea is that we should be able to see which u-boot version (a software partnumber) we are running from the kernel /proc/cmdline.
