Dear All,
I am using Power PC. The system which I am using takes 2 minutes more than
usual for the software in the system to come up without cache
enabling. These 2 minutes are really crucial.
But there are problems when I enabled cache. The devices which I am using
are mmapped. I do not want cache to be enabled for the memory mapped
devices. When cache is enabled, none of the mmapped devices work in the
usual way. How do I selectively disable the cache for the mmapped devices?
Thank you,
Deepesh

I had enabled the Data Cache. I forgot to mention that.
