xtensa: move headers files to arch/xtensa/include

2008-11-06T18:25:09+00:00

Move all header files for xtensa to arch/xtensa/include and platform and
variant header files to the appropriate arch/xtensa/platforms/ and
arch/xtensa/variants/ directories.

Moving the files gets also rid of all uses of symlinks in the Makefile.

This has been completed already for the majority of the architectures
and xtensa is one out of six missing.

xtensa: Fix io regions

2008-10-21T16:08:31+00:00

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.

[XTENSA] Add support for cache-aliasing

2007-08-27T20:54:16+00:00

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 files

2006-12-10T17:55:39+00:00

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.
