I think part of the problem is that wks files are tied to a rootfs image,
so it's not currently possible to have multiple because there is no way to
differentiate them. Also because of that it's a little odd to have a wks
file that doesn't reference the rootfs it's built with.

You might be able to do it by making a simple dummy image recipe for the
boot partition(s), then overriding the WKS_FILE variable for the image with
a pn override in the machine.conf file (e.g. WKS_FILE_pn-my-emmc-boot =
"emmc-boot.wks" )
