[U-Boot] Merge window questions

2008-09-11 Thread Peter Tyser
Hello,
I'm assuming the merge window has been closed based on
http://www.denx.de/wiki/U-Boot/ReleaseCycle and the fact that
v2008.10-rc1 has been tagged.

Does U-Boot accept new drivers/board support patches (ie new features
which can't regress) outside of merge windows, or only bug fixes?

My understanding for the Linux kernel is that self-contained
drivers/features are sometimes accepted after the merge window as they
shouldn't cause the kernel to regress as no old code is using them.

I have patches for a new MPC8572-based board and was wondering if I
should go ahead and send them out now, or wait until the next release in
~a month.  I see other non-bugfix patches still being sent to the
mailing list which gave me a glimmer of hope of getting the changes in
the upcoming 2008.10 release:)

Thanks for any insight,
Peter

Like in Linux, only bug fixes are accepted. 

There is no such thing as new code that can't regress. Please see
also the recent discussion about this on LKML and Linus' clear
statements:
http://thread.gmane.org/gmane.linux.network/104943/focus=104951

 shouldn't cause the kernel to regress as no old code is using them.

That used to be the case in Linux, and it turned out that it didn't
work that well. We don't do this here.

You  better  wait  a  while.  Especially  Jean-Christophe's  Makefile
patches will go in soon (as last bigger change in this release cycle)
and these would certainly break your patch.

Once Jean-Christophe's Makefile patches have been  applied  (and  any
problems  caused  by them fixed), I ill issue -rc2, and then probably
create a next branch. This might be used as a base for things  like
your patches.

Best regards,

Wolfgang Denk
