Re: UTOPIA support for MPC885 with 2.6.15 kernel

[Alex Zeffertt <ajz@cambridgebroadband.com>]

Hi Dave,

I maintain the mpc860sar project - although it hasn't required much
maintenance for the past year or so.

Nobody has told me about any linux-2.6 port, so it's possible you are
the first to do this.

If you are happy with your port I'd appreciate it if you sent me a
patch which I would then consider adding to the site.

FYI, I also maintain a  PQII driver called mpc8260sar, and I have
been sent a patch which added support for linux-2.6 without breaking
linux-2.4, so I added this to the sourceforge project.  If you like
I'll send you the PQII linux-2.6 patch as a guide for how to do it for
the original PQI driver.

Alex
