soc: sifive: ccache: Rename SiFive L2 cache to Composable cache.
Since composable cache may be L3 cache if there is a L2 cache, we should
use its original name composable cache to prevent confusion.

There are some new lines were generated due to adding the compatible
"sifive,ccache0" into ID table and indent requirement.

The sifive L2 has been renamed to sifive CCACHE, EDAC driver needs to
apply the change as well.

Masahiro Yamada a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Michael Ellerman 2b8358a951 EDAC/mpc85xx: Prevent building as a module
The mpc85xx EDAC driver can be configured as a module but then fails to

  ERROR: ".pci_find_hose_for_OF_device" [drivers/edac/mpc85xx_edac_mod.ko] undefined!
  ERROR: ".early_find_capability" [drivers/edac/mpc85xx_edac_mod.ko] undefined!

We don't want to export those symbols just for this driver, so make the
driver only configurable as a built-in.

This seems to have been broken since at least

The CONFIG_ALTERA_EDAC Kconfig symbol always enables the SDRAM EDAC
functionality. On the newer architectures, however, there are cases
where the peripheral EDAC functionality is enabled but SDRAM needs to be
disabled.

Move SDRAM functions so they can be contained inside the conditional
CONFIG. Create new CONFIG option just for SDRAM.

Qiuxu Zhuo d4dc89d069 EDAC, i10nm: Add a driver for Intel 10nm server processors
This driver supports the Intel 10nm series server integrated memory
controller. It gets the memory capacity and topology information by
reading the registers in PCI configuration space and memory-mapped I/O.

It decodes the memory error address to the platform specific address
by using the ACPI Address Translation (ADXL) Device Specific Method
(DSM).

Luck, Tony 24c9d423e8 EDAC, skx: Fix randconfig builds in a better way
It was previously noted that Kconfig complained about unmet dependencies
when trying to configure skx_edac together with CONFIG_ACPI=n. First fix
for this checked for ACPI when doing

  select ACPI_ADXL

but this required stub functions for the case where ACPI wasn't
selected. It also allowed building a driver that didn't actually work
for a system that has non-volatile DIMMs.

Arnd Bergmann pointed out that the right fix is to make EDAC_SKX
"depend on ACPI".

2018-11-02 11:17:22 -07:00
Borislav Petkov a324e9396c EDAC, skx: Fix randconfig builds
The driver depends on the ADXL component glue and selects it. However,
ADXL itself implicitly depends on ACPI and in nonsensical randconfig
builds like this:

  # CONFIG_ACPI is not set
  CONFIG_ACPI_ADXL=y

where ACPI is not enabled, the build fails with:

  drivers/edac/skx_edac.o: In function `skx_mce_check_error':
  skx_edac.c:(.text+0xab): undefined reference to `adxl_decode'
  drivers/edac/skx_edac.o: In function `skx_init':
  skx_edac.c:(.init.text+0x8bf): undefined reference to `adxl_get_component_names'
  make: *** [vmlinux] Error 1

Add stubs for that case so that the build succeeds. CONFIG_ACPI=n
doesn't make any sense for real configurations but this fix will at
least silence randconfig builds.

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

 "A lot of movement in the EDAC tree this time around, coarse summary
  below:

   - Altera Arria10 enablement of NAND, DMA, USB, QSPI and SD-MMC FIFO
     buffers (Thor Thayer)

   - split the memory controller part out of mpc85xx and share it with a
     new Freescale ARM Layerscape driver (York Sun)

   - amd64_edac fixes (Yazen Ghannam)

   - misc cleanups, refactoring and fixes all over the place"
