Lets try and stop this again here.  I think perhaps the KVM tool example
is instructive here.  For the various reasons that close association
with the kernel can be helpful for things (the exposure and ease of
being found), it would be nice if the tooling to expand single kernel
image into single "bootable" image was with the kernel.  But it's not a
requirement.  And it's not even necessarily the best for the tooling
either.  So, lets drop the idea of getting this into the kernel and if
people really do wish to extend FIT such that we can easily spit out a
FIT image that works on omap* and tegra* or what have you, and add a FIT
parser to GRUB, great, get to work.  No need to be tied to the kernel
for this.
