Re: [PATCH v3] libfdt: Add support for using aliases in fdt_path_offset()

Hmm.. my reading of 1275 says that an alias pointing to another alias
is not permitted, but I'm not terribly confident I'm not misreading
it.  Segher, do you know whether this is allowed?

My reading is the same: if after expanding an alias the path does
not start with "/", the search starts at the current package,
otherwise it starts at the root node; and no further alias expansion
is done.

It's a corner case for sure, but at least the standard doesn't
require us to implement recursive alias expansion; let's see if
common practice does ;-)
