Hi Jerzy

Thank you for sharing your eCos porting plans/progress.

Start as you have done, by talking about your plans on the ecos-devel
mailing list and giving other people in the community an opportunity to
comment.

Is your port based on current CVS?

As with Richard Rauch's port to AT91SAM9G45, you should bear in mind the
patch of Evgeniy Dushistov which re-organises the ARM7/ARM9 abstraction:

  http://bugs.ecos.sourceware.org/show_bug.cgi?id=1000819

We really must get Evgeniy's patch reviewed as soon as possible.

Initially I looked into patches but I didn't find any new rules. 
Could you shortly explain new approach?

If the patch does not impact STR9 porting, then working out of CVS is
ideal. I will add your project to the list. A couple of further points:

a) Please be prepared to share your development code in advance of the
contribution if anyone is interested.

b) Sorting out the copyright assignment to the FSF can take some time. I
recommend that you start this process in advance of your contribution to
avoid unnecessary delay. Details at:

Why couldn't open source mean only programming? I hoped that signature with 
eCos copyright and author/contributor name is sufficient.
