0616fb003d edac: i5400 fix missing CONFIG_PCI define
When building without CONFIG_PCI the edac_pci_idx variable is unused,
causing a build-time warning.  Wrap the variable in #ifdef CONFIG_PCI,
just like the rest of the PCI support.

b484625172 edac: mpc85xx add mpc83xx support
Add support for the Freescale MPC83xx memory controller to the existing
driver for the Freescale MPC85xx memory controller.  The only difference
between the two processors are in the CS_BNDS register parsing code, which
has been changed so it will work on both processors.

The L2 cache controller does not exist on the MPC83xx, but the OF
subsystem will not use the driver if the device is not present in the OF
device tree.

I had to change the nr_pages calculation to make the math work out.  I
checked it on my board and did the math by hand for a 64GB 85xx using 64K
pages.  In both cases, nr_pages * PAGE_SIZE comes out to the correct
value.

a014554e66 edac: mpc85xx add P2020DS support
Based on Kumar's new compatible types patch, add P2020 into MPC85xx EDAC
compatible lists so that EDAC can recognize P2020 meomry controller and L2
cache controller and export the relevant fields to sysfs.

EDAC MPC85xx DDR3 support is needed if DDR3 memory stick is installed on a
P2020DS board so that EDAC core can recognize DDR3 memory type.

b1cfebc923 edac: add DDR3 memory type for MPC85xx EDAC
Since some new MPC85xx SOCs support DDR3 memory now, so add DDR3 memory
type for MPC85xx EDAC.

55e5750b3e edac: ppc mpc85xx fix mc err detect
Error found by Jeff Haran.

The error detect register is 0s when no errors are detected.  The check
code is incorrect, so reverse check sense.

29d6cf26a7 edac: fix mpc85xx and add mpc8536 mpc8560
All other compatibles that are uniquely identifying the processor use a
prefix of the form fsl,mpc85...'.  We add support for it so we can
deprecate the older 'fsl,85...' that was improperly used here.

Additionally added mpc8536 & mpc8560 to the compatible lists.

This patch is based on Nate's 8572 patch.

60be75515e edac mpc85xx: add support for mpc8572
This adds support for the dual-core MPC8572 processor.  We have
to support making SPR changes on each core.  Also, since we can
have multiple memory controllers sharing an interrupt, flag the
interrupts with IRQF_SHARED.
