* xtensa: Fix io regionsChris Zankel2008-10-211-3/+5
| | | | | | | The uncached area starts at e000.0000 and spans 1GB. Also add an IOADDR macro to determine the bypass region to access the IO space. Signed-off-by: Chris Zankel <chris@zankel.net>
* [XTENSA] Add support for cache-aliasingChris Zankel2007-08-271-0/+1
| | | | | | | | | | | | | Add support for processors that have cache-aliasing issues, such as the Stretch S5000 processor. Cache-aliasing means that the size of the cache (for one way) is larger than the page size, thus, a page can end up in several places in cache depending on the virtual to physical translation. The method used here is to map a user page temporarily through the auto-refill way 0 and of of the DTLB. We probably will want to revisit this issue and use a better approach with kmap/kunmap.

* [PATCH] xtensa: remove extra header filesChris Zankel2006-12-101-32/+32
| | | | | | | | | | | The Xtensa port contained many header files that were never needed. This rather lengthy patch removes all those files. Unfortunately, there were many dependencies that needed to be updated, so this patch touches quite a few source files.
