Joe Perches 956b9ba156 edac: Convert debugfX to edac_dbg(X,
Use a more common debugging style.

Remove __FILE__ uses, add missing newlines,
coalesce formats and align arguments.

Mauro Carvalho Chehab c56087595f amd64_edac: convert sysfs logic to use struct device
Now that the EDAC core supports struct device, there's no sense
on having any logic at the EDAC core to simulate it. So, instead
of adding such logic there, change the logic at amd64_edac to
use it.

Borislav Petkov b2b0c60543 amd64_edac: Add support for F15h DCT PCI config accesses
F15h "multiplexes" between the configuration space of the two DRAM
controllers by toggling D18F1x10C[DctCfgSel] while F10h has a different
set of registers for DCT0, and DCT1 in extended PCI config space.

Add DCT configuration space accessors per family thus wrapping all the
different access prerequisites. Clean up code while at it, shorten
names.

Borislav Petkov 94baaee494 amd64_edac: beef up DRAM error injection
When injecting DRAM ECC errors (F3xBC_x8), EccVector[15:0] is a bitmask
of which bits should be error injected when written to and holds the
payload of 16-bit DRAM word when read, respectively.

Add /sysfs members to show the DRAM ECC section/word/vector.

Fail wrong injection values entered over /sysfs instead of truncating
them.
