crt0.S: How to submit updates, what else to change etc.?

[Toralf Lund]

As I mentioned earlier, I'm using a modified version of arm/crt0.S for 
my OS-less, no-debug-monitor app. I think my changes are fairly general 
and may be useful to others working on similar setups, so I though I 
might try to feed them back into the newlib sources. However, I'm not 
exactly sure what I need to do to fully complete the update, or how I 
should proceed once I have.

Questions:

   1. Where do I submit newlib patches?
   2. Why is the generic start code for a CPU-type sometimes found in
      libgloss, sometimes in newlib/sys? The one I'm talking about came
      from newlib, but after my changes it may resemble some of the ones
      found in libgloss more closely.
   3. The update changes requirements to the linker scripts. Which files
      should I edit to reflect these?
   4. Anything else I ought to update to keep the setup consistent?
