751ca492f1 dt-bindings: PCI: imx6: convert the imx pcie controller to dtschema 
Convert the fsl,imx6q-pcie.txt into a schema.
- ranges property should be grouped by region, with no functional
  changes.
- only one propert is allowed in the compatible string, remove
  "snps,dw-pcie".

1c3ac086fd dt-bindings: Use 'enum' instead of 'oneOf' plus 'const' entries 
'enum' is equivalent to 'oneOf' with a list of 'const' entries, but 'enum'
is more concise and yields better error messages.

2931ea847d riscv: Remove non-standard linux,elfcorehdr handling 
RISC-V uses platform-specific code to locate the elf core header in
memory.  However, this does not conform to the standard
"linux,elfcorehdr" DT bindings, as it relies on a reserved memory node
with the "linux,elfcorehdr" compatible value, instead of on a
"linux,elfcorehdr" property under the "/chosen" node.

The non-compliant code can just be removed, as the standard behavior is
already implemented by platform-agnostic handling in the FDT core code.

f7e7ce93aa of: fdt: Add generic support for handling elf core headers property 
There are two methods to specify the location of the elf core headers:
using the "elfcorehdr=" kernel parameter, as handled by generic code in
kernel/crash_dump.c, or using the "linux,elfcorehdr" property under the
"/chosen" node in the Device Tree, as handled by architecture-specific
code in arch/arm64/mm/init.c.

Extend support for "linux,elfcorehdr" to all platforms supporting DT by
adding platform-agnostic handling for handling this property to the FDT
core code.  This can co-exist safely with the architecture-specific
handling, until the latter has been removed.

This requires moving the call to of_scan_flat_dt() up, as the code
scanning the "/chosen" node now needs to be aware of the values of
"#address-cells" and "#size-cells".

Make the forward declarations of elfcorehdr_addr and elfcorehdr_size,
and the definitions of ELFCORE_ADDR_MAX and ELFCORE_ADDR_ERR always
available, like is done for phys_initrd_start and phys_initrd_size.
Code referring to these symbols can then just check for
IS_ENABLED(CONFIG_CRASH_DUMP), instead of requiring conditional
compilation using an #ifdef, thus preparing to increase compile
coverage.

The 'contains' keyword applies to elements within an array, so
using 'items' only makes sense if the elements of the array are another

Looking at the driver, it seems the intent was the condition should be
true when 'faraday,ftpci100' is present, so we can drop
'cortina,gemini-pci'.

39c6b3a3dd of: fdt: Remove weak early_init_dt_mark_hotplug_memory_arch() 
Commit 41a9ada3e6 ("of/fdt: mark hotpluggable memory") introduced
two (for systems with and without memblock) weak versions of
early_init_dt_mark_hotplug_memory_arch(), that could be overridden by an
architecture-specific version.  However, no overrides ever emerged.
Later, commit aca52c3983 ("mm: remove CONFIG_HAVE_MEMBLOCK")
removed the non-memblock version.

Remove early_init_dt_mark_hotplug_memory_arch(), and replace it by a
direct call to memblock_mark_hotplug().
