Subject: [PATCH v4 0/6] arm64: Get rid of __early_init_dt_declare_initrd()
Date:   Mon,  5 Nov 2018 14:54:25 -0800

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.

  nds32: Remove phys_initrd_start and phys_initrd_size
  arch: Make phys_initrd_start and phys_initrd_size global variables
  of/fdt: Populate phys_initrd_start/phys_initrd_size from FDT
  arm64: Utilize phys_initrd_start/phys_initrd_size
  of/fdt: Remove custom __early_init_dt_declare_initrd() implementation
  arch: Move initrd= parsing into do_mounts_initrd.c
