Hi Boris,
This set contains a few fixes for some changes merged in v5.2. There
are also a couple of fixes for older issues. In addition, there are a
couple of patches to add support for Asymmetric Dual-Rank DIMMs.
Thanks,
Yazen

Currently, the DIMM info for AMD Family 17h systems is initialized in
init_csrows(). This function is shared with legacy systems, and it has a
limit of two channel support.
This prevents initialization of the DIMM info for a number of ranks, so
there will be missing ranks in
From: Yazen Ghannam
Chip Select memory size reporting on AMD Family 17h was recently fixed
in order to account for interleaving. However, the current method is not
robust.
The Chip Select Address Mask can be used to find the memory size. There
are a few cases.

From: Yazen Ghannam
AMD Family 17h systems have a set of secondary Chip Select Base
Addresses and Address Masks. These do not represent unique Chip
Selects, rather they are used in conjunction with the primary
Chip Select registers in certain use cases.

From: Yazen Ghannam
The struct chip_select array that's used for saving chip select bases
and masks is fixed at length of two. There should be one struct
chip_select for each controller, so this array should be increased to
support systems that may have more than two controllers.

Future AMD systems will support "Asymmetric" Dual-Rank DIMMs. These are
DIMMs were the ranks are of different sizes.
The even rank will use the Primary Even Chip Select registers and the
odd rank will use the Secondary Odd Chip Select registers.

AMD Family 17h systems currently require address translation in order to
report the system address of a DRAM ECC error. This is currently done
before decoding the syndrome information. The syndrome information does
not depend on the address translation, so the proper EDAC csro
From: Yazen Ghannam
AMD Family 17h systems support x4 and x16 DRAM devices. However, the
device type is not checked when setting EDAC_CTL_CAP.
Set the appropriate EDAC_CTL_CAP flag based on the device type.

The number of MCA banks is provided per logical CPU. Historically, this
number has been the same across all CPUs, but this is not an
architectural guarantee. Future AMD systems may have MCA bank counts
that vary between logical CPUs in a system.
This issue was partially addre

The OS is expected to write all bits in MCA_CTL. However, only
implemented bits get set in the hardware.
Read back MCA_CTL so that the value in the hardware is saved and
reported through sysfs.

From: Yazen Ghannam
The OS is expected to write all bits to MCA_CTL for each bank. However,
some banks may be unused in which case the registers for such banks are
Read-as-Zero/Writes-Ignored. Also, the OS may not write any control bits
because of quirks, etc.
A bank can be considered uninitiali
From: Yazen Ghannam
Current AMD systems have unique MCA banks per logical CPU even though
the type of the banks may all align to the same bank number. Each CPU
will have control of a set of MCA banks in the hardware and these are
not shared with other CPUs.
For example, bank 0 may be the Load-St

The struct mce_banks[] array is only used in mce/core.c so move the
definition of struct mce_bank to mce/core.c and make the array static.
Also, change the "init" field to bool type.

The focus of this patchset is define and use the MCA bank structures
and bank count per logical CPU.
With the exception of patch 4, this set applies to systems in production
today.
Patch 1:
