The wrong index into the csbases/csmasks arrays was being passed to
the function to compute the chip select sizes, which resulted in the
wrong size being computed. Address that so that the correct values are
computed and printed.
Also, redo how we calculate the number of pages in a CS row.

Apparently, some machines used to report DRAM errors through a PCI SERR
NMI. This is why we have a call into EDAC in the NMI handler. See
c0d121720220 ("drivers/edac: add new nmi rescan").
From looking at the patch above, that's two drivers: e752x_edac.c and
e7xxx_edac.c. Now, I wanna say those are old machines which are probably
decommissioned already.
Tony says that "[t]the newest CPU supported by either of those drivers
is the Xeon E7520 (a.k.a. "Nehalem") released in Q1'2010. Possibly some
folks are still using these ... but people that hold onto h/w for 7
years generally cling to old s/w too ... so I'd guess it unlikely that
we will get complaints for breaking these in upstream."
So even if there is a small number still in use, we did load EDAC with
edac_op_state == EDAC_OPSTATE_POLL by default (we still do, in fact)
which means a default EDAC setup without any parameters supplied on the
command line or otherwise would never even log the error in the NMI
handler because we're polling by default:
inline int edac_handler_set(void)
{
if (edac_op_state == EDAC_OPSTATE_POLL)
return 0;
return atomic_read(&edac_handlers);
}
So, long story short, I'd like to get rid of that nastiness called
edac_stub.c and confine all the EDAC drivers solely to drivers/edac/. If
we ever have to do stuff like that again, it should be notifiers we're
using and not some insanity like this one.

Initial target for this driver is the Intel Apollo Lake platform and
Denverton micro-server, they use the same internal memory controller IP
called Pondicherry2.
Memory controller registers are not in PCI config space like earlier
Intel memory controllers. For Apollo Lake platform they are accessed via
a "side-band" interface, for Denverton micro-server they are access via
PCI config space and memory map I/O. This driver is for Apollo Lake and
Denverton, but only the Denverton is fully enabled while we wait for the
sideband driver.

Currently, the IPID and Syndrome are printed on the same line as the
Address. There are cases when we can have a valid Syndrome but not a
valid Address.
For example, the MCA_SYND register can be used to hold more detailed
error info that the hardware folks can use. It's not just DRAM ECC
syndromes. There are some error types that aren't related to memory that
may have valid syndromes, like some errors related to links in the Data
Fabric, etc.
In these cases, the IPID and Syndrome are not printed at the same log
level as the rest of the stanza, so users won't see them on the console.
Console:
[Hardware Error]: CPU:16 (17:1:0) MC22_STATUS[Over|CE|MiscV|-|-|-|-|SyndV|-]: 0xd82000000002080b

Print the IPID first and on a new line. The IPID should always be

Having ECC disabled on a node doesn't necessarily mean that it's
disabled for the entire system. So let's return a non-failing code when
ECC is disabled on a node. This way we can skip initialization for the
node but still continue with the remaining nodes.
After probing all instances, make sure we have at least one MC device
allocated.
This issue is seen and fix tested on Fam15h and Fam17h MCM systems.

However, they are global and so don't need to be registered/unregistered

Some kernel-doc tags don't provide good descriptions or use
a different style. Adjust them.

Currently, there's no device driver documentation for the EDAC
subsystem at the driver-api book. Fill in the blanks for the
structures and functions that misses documentation, uniform
the word on the existing ones, and add a new edac.rst file at
driver-api, in order to document the EDAC subsystem.

Several functions are documented at edac_mc.c.
As we'll be including edac_core.h at drivers-api book, move
those, in order for the kernel-doc markups be part of the API
documentation book.

Several functions are documented at edac_pci.c and edac_pci_sysfs.c.
As we'll be including edac_pci.h at drivers-api book, move those,
in order for the kernel-doc markups be part of the API
documentation book.
As several of those kernel-doc macros are not in the right format,
fix them.
