Since the QPACE (Chromodynamics Parallel Computing on the
Cell Broadband Engine) platform doesn't use a iommu, doesn't
have PCI devices and a MPIC much lesser setup and
configurations are needed. So far all devices are detected
as OF device. A notifier function is used to set the dma_ops
for the of_platform bus. Further this patch splits the
PPC_CELL_NATIVE into PPC_CELL_COMMON which are parts that are
shared with the QPACE platform and the rest.

I wrote a new module for Intel X38 chipset. This chipset is very similar
to Intel 3200 chipset, but there are some different points, so I copyed
i3200_edac.c and modified.
This is Intel's web page describing this chipset.
http://www.intel.com/Products/Desktop/Chipsets/X38/X38-overview.htm
I've tested this new module with broken memory, and it seems to be working
well.

Preliminary support for the Intel 5100 MCH. CE and UE errors are reported
along with the current DIMM label information and other memory parameters.
Reasons why this is preliminary:
1) This chip has 2 independent memory controllers which, for best
perforance, use interleaved accesses to the DDR2 memory. This
architecture does not map very well to the current edac data structures
which depend on symmetric channel access to the interleaved data.
Without core changes, the best I could do for now is to map both memory
controllers to different csrows (first all ranks of controller 0, then
all ranks of controller 1). Someone much more familiar with the edac
core than I will probably need to come up with a more general data
structure to handle the interleaving and de-interleaving of the two
memory controllers.
2) I have not yet tackled the de-interleaving of the rank/controller
address space into the physical address space of the CPU. There is
nothing fundamentally missing, it is just ending up to be a lot of
code, and I'd rather keep it separate for now, esp since it doesn't
work yet...
3) The code depends on a particular i5100 chip select to DIMM mainboard
chip select mapping. This mapping seems obvious to me in order to
support dual and single ranked memory, but it is not unique and DIMM
labels could be wrong on other mainboards. There is no way to query
this mapping that I know of.
4) The code requires that the i5100 is in 32GB mode. Only 4 ranks per
controller, 2 ranks per DIMM are supported. I do not have hardware
(nor do I expect to have hardware anytime soon) for the 48GB (6 ranks
per controller) mode.
5) The serial presence detect code should be broken out into a "real"
i2c driver so that decode-dimms.pl can work.

Adds driver for the Cell memory controller when used without a Hypervisor such
as on the IBM Cell blades. There might still be some improvements to do to
this such as finding if it's possible to properly obtain more details about
the address of the error but it's good enough already to report CE counts
which is our main priority at the moment.

1) Remove an old CVS ID string
2) change EDAC from a tristate option to a simple bool option
3) In addition to the X86 arch, PPC and MIPS also have drivers in the
submission queue. This patch turns on the EDAC flag for those archs. Each
driver will have its respective 'depends on ARCH' set.

Provides a way for NMI reported errors on x86 to notify the EDAC
subsystem pending ECC errors by writing to a software state variable.
Here's the reworked patch. I added an EDAC stub to the kernel so we can
have variables that are in the kernel even if EDAC is a module. I also
implemented the idea of using the chip driver to select error detection
mode via module parameter and eliminate the kernel compile option.
Please review/test. Thx!
Also, I only made changes to some of the chipset drivers since I am
unfamiliar with the other ones. We can add similar changes as we go.

This is a subset of the bluesmoke project core code, stripped of the NMI work
which isn't ready to merge and some of the "interesting" proc functionality
that needs reworking or just has no place in kernel. It requires no core
kernel changes except the added scrub functions already posted.
The goal is to merge further functionality only after the core code is
accepted and proven in the base kernel, and only at the point the upstream
extras are really ready to merge.
From: doug thompson <norsk5@xmission.com>
This converts EDAC to sysfs and is the final chunk neccessary before EDAC
has a stable user space API and can be considered for submission into the
base kernel.
