That is about the same rule that I use; luckily (a credit to the Linux
kernel and other developers); I don't have to change much stuff like
that.

There is a grey zone, but let's talk about a specific case:

In my current queue, I have to write a Host Port Interface (HPI) protocol
(serial) to a TI DSP. I would imagine that this is a useful
contribution. However, using HPI is almost by nature limited to specific
embedded designs (most of which differ slightly from one another).
Furthermore; I will need to use a number of GPIO pins on a 834x
processor. Using this needs to be backed by configuration settings in
U-Boot. If someone else makes a similar design; it would most likely be
with another processor family; and even then; they'll have other pins
connected/used.

Though the protocol would be a real nice addition; the physical
connection/configuration make including it in the main kernel tree
difficult.

Even though I would welcome this; our boards are included in larger
expensive systems that would just be shipped back in case of problems;
but we've never had functional (linux) problems (yet).

Come to think of it, I have a number of minor patches for 8349SYS based
configurations; where can I find the last devel code (next to 2.6.17)
for patch creation (and to whom to send them back)?
