[PATCH v2 0/6] arm64: Get rid of __early_init_dt_declare_initrd()

From: Florian Fainelli
Date: Tue Oct 30 2018 - 19:07:49 EST


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.
