[PATCH v4 0/2] arm64: Get rid of __early_init_dt_declare_initrd()

[Florian Fainelli]

Hi all,

I numbered this v4 because this is still revolving around the same
initial desire to cut the build time of an ARM64 kernel when toggling
CONFIG_BLK_DEV_INITRD. This 4th version is basically the 3rd possible
way to just get rid of __early_init_dt_declare_initrd() for ARM64.

I previously mentioned that I was working on making
phys_initrd_start/phys_initrd_size generic across architectures that
make use of it, which would cover ARM (32-bit), unicore32 and possibly
arm64, but upon second glance, this does not necessarily help, or rather
this patch series actually helps make a smoother conversion in the
future.

Comments welcome, sorry for making so many iterations, it's Friday.

v3:

v2:
https://lkml.org/lkml/2018/10/25/4


Changes in v4:

- perform the physical to virtual initrd conversion straight within
  arm64_memblock_init() to get the correct memblock reservation to occur

Changes in v3:
- attempt to change drivers/of/fdt.c to absorb ARM64's specific behavior

Changes in v2:

- put an /* empty */ comment in the asm-generic/initrd.h file
- trim down the CC list to maximize the chances of people receiving this
