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/'

9209fb5189 riscv: move sifive_l2_cache.c to drivers/soc
The sifive_l2_cache.c is in no way related to RISC-V architecture
memory management.  It is a little stub driver working around the fact
that the EDAC maintainers prefer their drivers to be structured in a
certain way that doesn't fit the SiFive SOCs.

Move the file to drivers/soc and add a Kconfig option for it, as well
as the whole drivers/soc boilerplate for CONFIG_SOC_SIFIVE.

2b8358a951 EDAC/mpc85xx: Prevent building as a module
The mpc85xx EDAC driver can be configured as a module but then fails to
build because it uses two unexported symbols:

  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

  c92132f598 ("edac/85xx: Add PCIe error interrupt edac support")

(Nov 2013).

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.

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".

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.

27450653f1 drivers: edac: Add EDAC driver support for QCOM SoCs
Add error reporting driver for Single Bit Errors (SBEs) and Double Bit
Errors (DBEs). As of now, this driver supports error reporting for
Last Level Cache Controller (LLCC) of Tag RAM and Data RAM. Interrupts
are triggered when the errors happen in the cache, the driver handles
those interrupts and dumps the syndrome registers.

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.

4ec656bdf4 EDAC, skx_edac: Add EDAC driver for Skylake
This is an entirely new driver instead of yet another set of patches
to sb_edac.c because:

1) Mapping from PCI devices to socket/memory controller is significantly
   different. Skylake scatters devices on a socket across a number of
   PCI buses.
2) There is an extra level of interleaving via the "mcroute" register
   that would be a little messy to squeeze into the old driver.
3) Validation is getting too expensive. Changes to sb_edac need to
   be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and
   Knights Landing.

b01aec9b2c EDAC: Cleanup atomic_scrub mess
So first of all, this atomic_scrub() function's naming is bad. It looks
like an atomic_t helper. Change it to edac_atomic_scrub().

The bigger problem is that this function is arch-specific and every new
arch which doesn't necessarily need that functionality still needs to
define it, otherwise EDAC doesn't compile.

So instead of doing that and including arch-specific headers, have each
arch define an EDAC_ATOMIC_SCRUB symbol which can be used in edac_mc.c
for ifdeffery. Much cleaner.

And we already are doing this with another symbol - EDAC_SUPPORT. This
is also much cleaner than having CONFIG_EDAC enumerate all the arches
which need/have EDAC support and drivers.

This way I can kill the useless edac.h header in tile too.

7e52a03646 EDAC, altera: Do not build it as a module
The SDRAM EDAC requires SDRAM configuration/initialization before SDRAM
is accessed (in the preloader) and therefore before Linux is loaded.
Having a module compile is not desired so force to be built into kernel.

ae9b56e399 EDAC, synps: Add EDAC support for zynq ddr ecc controller
Add EDAC support for ecc errors reporting on the synopsys ddr
controller. The ddr ecc controller corrects single bit errors and
detects double bit errors.

Selected important-ish notes from the changelog:

- I have not taken care of spliting synps_edac_geterror_info function as
it adds additional indentation levels and moreover the existing changes
were made as part of the v2 review comments

- Removed dt binding info as already there is a binding info available
under memorycontroller. so, updated ecc info there.

- Shortened the prefix "sysnopsys" to "synps"
