After syncing the sunxi dts files with the upstream kernel dm/fdt sunxi
builds would no longer boot.

The problem is that stdout-path is now set like this in the upstream
dts
files: stdout-path = "serial0:115200n8". The use of options in
of-paths,
either after an alias name, or after a full path, e.g. stdout-path =
"/soc@01c00000/serial@01c28000:115200", is standard of usage, but
something
which the u-boot dts code so far did not handle.

This commit fixes this, adding support for both path formats.

I haven't looked. but is this change in dtc upstream or just in the
kernel?



This is just a change in the dts files shipped with the kernel not in
dtc,
the dts files for sunxi used to not set stdout-path, and you patched in
a stdout-path setting for u-boot:


In that case, can we change this in the fdt support /fdtdec code,
instead of making a change to libfdt that will never go upstream?

If that doesn't work or is too painful, then we should take this patch.


Actually I started with fixing this the fdtdev level, but then I noticed
that the kernel does this at the of_find_node_by_path level, so if we
fix this for stdout-path only (which a fdtdec patch would do) then we may
get bit by this again later.

Also fixing it at the fdtdec level means adding a strdup + error checking
since then we need to pass a truncated (options removed) copy of the path
to fdt_path_offset(), while with the current patch we can keep using
read only access to the fdt.

So I've a slight preference for going this way. Why would libfdt upstream
not
take this patch ?

I'm not sure, but please go ahead and send it upstream. Thanks for the
explanation, I'll pick this up.

Can I just check if you are OK to send this upstream? We don't need to
wait for it to be accepted, just want to know it will be sent.

Yes I will submit this upstream.

Regards,

Hans
