I guess you're suggesting that this wrapper uses libfdt to merge
the ATAGs with the DT info?
I think this is getting messy - and I think that we've made a design
error with the boot process in thinking that we'll have either ATAGs
_or_ DT. While we can continue to stuff the early kernel parts like
decompressors and such like with this stuff, it's getting painful and
It would have been far better to have passed both the ATAGs _and_ DT
to the kernel directly and let it sort them out without having to
teach several layers about DT parsing.
