Subject: [PATCH v2 0/6] arm64: Get rid of __early_init_dt_declare_initrd()
Date: Tue, 30 Oct 2018 16:07:15 -0700	[thread overview]
Message-ID: <20181030230721.28429-1-f.fainelli@gmail.com> (raw)

Hi all,

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.

Florian Fainelli (6):
  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
