Why build bootldr, u-boot, and kernel separate from rootfs?

According to linux4sam/bin/view/Linux4SAM/Sama5d3XplainedMainPage, one should build the bootloader, u-boot, and kernel separately from the Yocto based rootfs. Why is that? The Yocto build recipe generates these build targets. Are they known to work? Are they known not to work?

You seem to be reading something that is not there, i.e. there is no "should".

I'm not the author of that web page, but IMO the intent seems to be about teaching the components involved in building and booting the system.
If you simply build everything using just one command line, how do you actually learn to differentiate the components?
