Hi all, Changes in v4: - dropped initrd_below_start_ok assignment in ARM64, not necessary at all (Ard) - replace #ifdef CONFIG_BLK_DEV_INITRD with if (IS_ENABLED(CONFIG_BLK_DEV_INITRD) for consistency with other parts of arm64_memblock_init() (Rob) Changes in v3: - use C conditionals in drivers/of/fdt.c - added check on phys_initrd_size in arch/arm64/mm/init.c to determine whether initrd_start must be populated - fixed a build warning with ARC that was just missing an (unsigned long) cast Changes in v2: - get rid of ARCH_HAS_PHYS_INITRD and instead define phys_initrd_start/phys_initrd_size in init/do_mounts_initrd.c - make __early_init_dt_declare_initrd() account for ARM64 specific behavior with __va() when having CONFIG_DEBUG_VM enabled - consolidate early_initrd() command line parsing into init/do_mounts_initrd.c Because phys_initrd_start/phys_initrd_size are now compiled in ini/do_mounts_initrd.c which is only built with CONFIG_BLK_DEV_INITRD=y, we need to be a bit careful about the uses throughout architecture specific code.
