I'm doing some fairly massive rework to my patches so it'll take
another day or two (plus 4 day weekend for me). In the meantime,
this is what I've done to your code. :)
Any further progress on this? I need an ft library for the prep
bootwrapper changes I'm planning.
I don't like the approach of doing a malloc for the whole blob every
time you make a property larger though. I'm going to be adding quite
a few nodes and properties, potentially, and with a simple-minded
malloc (such as you get in a bootwrapper) it's likely to chew through
a lot of memory unnecessarily. I would rather be able to start with
an existing blob and pull it apart once, add stuff to it, then put it
back together, doing a small number of mallocs in the process.

I still plan on changing it a bit to use ft_next in a few more routines
(e.g., ft_dump_blob). ft_next has a clumsy interface but I like the fact
The interface might look nicer if we had a structure for the tag,
name, value and length. Then there would only be one parameter
instead of the four you have at the moment.

Paul,
Here's what I have at the moment...
- flatdevtree.[ch] are copies of what Hollis will be keeping (but I've
edited the ones attached to this email)
- flatdevtree_env.h is a bootwrapper hdr file that contains local
defines that the generic flatdevtree.[ch] need
- flatdevtree_misc.c is other ft stuff that isn't in flatdevtree.c plus
some bootwrapper->flatdevtree.c glue code
