OpenRISC Architecture: Patch set version 2

From: Jonas Bonn
Date: Sat Jul 02 2011 - 17:16:20 EST


This is version 2 of the OpenRISC architecture patch set. Changes
since version 1 include:

- general cleanups, removing unused code and variables, taking care of
compiler warnings, etc.
- cleanups for all the errors spotted by checkpatch.pl
- changes in response to the feedback received for version 1 of the patch set
- simplification of the fixmap code
- simplification of the DMA code
- calculate loops_per_jiffy from cpu frequency passed in via devicetree
- rework io.h to use more generic code
- rework the delay code, making it more generic

- also, the module code has been reworked, making it more generic; this is
not included in this patch as the generic parts are still pending review

Since version 1:
54 files changed, 793 insertions(+), 1900 deletions(-)

Once again, all this code can be found in the 'for-upstream' branch at:

git://openrisc.net/jonas/linux

Note, that there are three patches at the base of the branch that make
some changes to generic kernel code that are necessary for the OpenRISC
patches to work. Those patches aren't included in this post as they have
already been posted for review earlier.
