This is going to break users who rely on the existing naming/layout. 

The patch description is lacking on why we need to do this too, it just says what you're doing and not why.

[Liu Ting-B28495] on our side, we used two ways to load the kernel images. 1) load from Ethernet 2) load from hard disk which deployed with the rootfs image containing kernel image (installing the package 'kernel-image'). We cannot use the same bootargs in u-boot due to the mismatched name.
