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.

Add support for handling the "linux,usable-memory-range" property in the "/chosen" node to the FDT core code. This can co-exist safely with the architecture-specific handling, until the latter has been removed. Signed-off-by:

Geert Uytterhoeven authored
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". Signed-off-by:

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 array which is not the case for 'compatible' properties. 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'.

Commit 41a9ada3 ("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 aca52c39 ("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(). Signed-off-by:
