The L2 cache controller on the T2080 SoC has similar capabilities to the
others already supported by the mpc85xx_edac driver. Add it to the list
of compatible devices.

If we execute the below steps without this patch:
modprobe mpc85xx_edac [The first insmod, everything is well.]
modprobe -r mpc85xx_edac
modprobe mpc85xx_edac [insmod again, error happens.]
We would get the error messages as below:

We'd like to eventually remove NO_IRQ on powerpc, so remove usages of it
from powerpc-only drivers.
The pdata structs are kzalloc'ed, so we don't need to initialise those
to 0, we can just drop the assignments entirely.

On e500v1, read fault exception enable (RFXE) controls whether assertion
of core_fault_in causes a machine check interrupt. Assertion of
core_fault_in can result from uncorrectable data error, such as an L2
multi-bit ECC error. It can also occur from a system error if logic on
the integrated device signals a fault for nonfatal errors. RFXE bit is
cleared out of reset, and should be left clear for normal operation.
Assertion of core_fault_in does not cause a machine check.
RFXE is set specifically for RIO (Rapid IO) and PCI for book E to catch
the errors by machine check. With this bit set, the EDAC driver can't
get the interrupt in case of uncorrectable error. So this bit is cleared
in favor of EDAC. However, the benefit of catching such uncorrectable
error doesn't outweigh the other errors which may hang the system.
Besides, e500v2 has different errors masked by RFXE, and e500mc doesn't
support this bit. It is more reasonable to leave RFXE as is in the EDAC
driver, and leave the uncorrectable errors triggering machine check for
e500v1.

Originally the mpc85xx-pci-edac driver bound directly to the PCI
controller node.
Commit
905e75c46dba ("powerpc/fsl-pci: Unify pci/pcie initialization code")
turned the PCI controller code into a platform device. Since we can't
have two drivers binding to the same device, the EDAC code was changed
to be called into as a library-style submodule. However, this doesn't
work if the EDAC driver is built as a module.
Commit
8d8fcba6d1ea ("EDAC: Rip out the edac_subsys reference counting")
exposed another problem with this approach -- mpc85xx_pci_err_probe()
was being called in the same early boot phase that the PCI controller
is initialized, rather than in the device_initcall phase that the EDAC
layer expects. This caused a crash on boot.
To fix this, the PCI controller code now creates a child platform device
specifically for EDAC, which the mpc85xx-pci-edac driver binds to.

Add pcie error interrupt edac support for mpc85xx, p3041, p4080, and
p5020. The mpc85xx uses the legacy interrupt report mechanism - the
error interrupts are reported directly to mpic. While the p3041/
p4080/p5020 attaches the most of error interrupts to interrupt zero. And
report error interrupts to mpic via interrupt 0.
This patch can handle both of them.

We unified the Freescale pci/pcie initialization by changing the fsl_pci
to a platform driver. In previous PCI code architecture the initialization
routine is called at board_setup_arch stage. Now the initialization is done
in probe function which is architectural better. Also It's convenient for
adding PM support for PCI controller in later patch.
Now we registered pci controllers as platform devices. So we combine two
initialization code as one platform driver.

In order to avoid loosing error events, it is desirable to group
error events together and generate a single trace for several identical
errors.
The trace API already allows reporting multiple errors. Change the
handle_error function to also allow that.
The changes at the drivers were made by this small script:
$file .=$_ while (<>);
$file =~ s/(edac_mc_handle_error)\s*\(([^\,]+)\,([^\,]+)\,/$1($2,$3, 1,/g;
print $file;

Remove the arch-dependent parameter, as it were not used,
as the MCE tracepoint weren't implemented. It probably doesn't
make sense to have an MCE-specific tracepoint, as this will
cost more bytes at the tracepoint, and tracepoint is not free.
The changes at the EDAC drivers were done by this small perl script:
$file .=$_ while (<>);
$file =~ s/(edac_mc_handle_error)\s*\(([^\;]+)\,([^\,\)]+)\s*\)/$1($2)/g;

The debug macro already adds that. Most of the work here was

$f =~ s/(debugf[0-9]\s*\(\s*)__FILE__\s*/\1/g;
$f =~ s/(debugf[0-9]\s*\(\s*)__FILE__\s*"MC: /\1"/g;
$f =~ s/(debugf[0-9]\s*\(\")\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+)__func__\s*\,\s*/\1\2/g;
$f =~ s/(debugf[0-9]\s*\(\")\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+),\s*__func__\s*\)/\1\2)/g;

$f =~ s/(debugf[0-9]\s*\(\"MC\:\s*)\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+),\s*__func__\s*\)/\1\2)/g;
$f =~ s/\"MC\: \\n\"/"MC:\\n"/g;
print $f;
After running the script, manual cleanups were done to fix it the remaining
places.
While here, removed the __LINE__ on most places, as it doesn't actually give
useful info on most places.

Kernel kobjects have rigid rules: each container object should be
dynamically allocated, and can't be allocated into a single kmalloc.
EDAC never obeyed this rule: it has a single malloc function that
allocates all needed data into a single kzalloc.
As this is not accepted anymore, change the allocation schema of the
EDAC *_info structs to enforce this Kernel standard.

As EDAC doesn't use struct device itself, it created a parent dev
pointer called as "pdev". Now that we'll be converting it to use
struct device, instead of struct devsys, this needs to be fixed.
No functional changes.

commit ca0907b "edac: Remove the legacy EDAC ABI" broke mpc85xx_edac
in the following manner:
mpc85xx_edac.c:983:35: error: too few arguments to function 'edac_mc_alloc'
this patch puts back the missing 'layers' argument.

The number of pages is a dimm property. Move it to the dimm struct.
After this change, it is possible to add sysfs nodes for the DIMM's that
will properly represent the DIMM stick properties, including its size.
A TODO fix here is to properly represent dual-rank/quad-rank DIMMs when
the memory controller represents the memory via chip select rows.

On systems based on chip select rows, all channels need to use memories
with the same properties, otherwise the memories on channels A and B
won't be recognized.
However, such assumption is not true for all types of memory
controllers.
Controllers for FB-DIMM's don't have such requirements.
Also, modern Intel controllers seem to be capable of handling such
differences.
So, we need to get rid of storing the DIMM information into a per-csrow
data, storing it, instead at the right place.
The first step is to move grain, mtype, dtype and edac_mode to the
per-dimm struct.

.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver. This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.
This patch is a pretty mechanical change. The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial. This patch looks big and scary because it touches so
many files, but it should be pretty safe.
