Commit 7536c7e03e74 ("of/fdt: Remove redundant kbasename function
call") exposed a bug creating DT nodes in the ATAGS to DT fixup code.
Non-existent nodes would mistaken get created with a leading '/'. The
problem was fdt_path_offset() takes a full path while creating a node
with fdt_add_subnode() takes just the basename.

Since this we only add root child nodes, we can just skip over the '/'.

Thanks for the quick patch. It doesn't quite seem to work as my system 
can't find it's initrd (it can with my other hacky patch). It does seem 
to get the command line info as I'm getting printk output.

That doesn't make sense. Can you enable debug in drivers/of/fdt.c.

I've attached two captures with DEBUG enabled in drivers/of/fdt.c. One 
with your patch and one with mine. I note that in your one we do 
actually pick up initrd_start/initrd_end but then it gets disabled for 
some reason (possibly other changes we have in our kernel).

I've attached two captures with DEBUG enabled in drivers/of/fdt.c. One 
with your patch and one with mine. I note that in your one we do 
actually pick up initrd_start/initrd_end but then it gets disabled for 
some reason (possibly other changes we have in our kernel).
