Subject: [PATCH v4 0/6] arm64: Get rid of __early_init_dt_declare_initrd()
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.
