Hi all,

While investigating why ARM64 required a ton of objects to be rebuilt
when toggling CONFIG_DEV_BLK_INITRD, it became clear that this was
because we define __early_init_dt_declare_initrd() differently and we do
that in arch/arm64/include/asm/memory.h which gets included by a fair
amount of other header files, and translation units as well.

This patch series proposes adding an empty initrd.h to satisfy the need
for drivers/of/fdt.c to unconditionally include that file, and moves the
custom __early_init_dt_declare_initrd() definition away from
asm/memory.h

This cuts the number of objects rebuilds from 1920 down to 26, so a
factor 73 approximately.

Apologies for the long CC list, please let me know how you would go
about merging that and if another approach would be preferable, e.g:
introducing a CONFIG_ARCH_INITRD_BELOW_START_OK Kconfig option or
something like that.

Hi all,

While investigating why ARM64 required a ton of objects to be rebuilt
when toggling CONFIG_DEV_BLK_INITRD, it became clear that this was
because we define __early_init_dt_declare_initrd() differently and we do
that in arch/arm64/include/asm/memory.h which gets included by a fair
amount of other header files, and translation units as well.

This patch series proposes adding an empty initrd.h to satisfy the need
for drivers/of/fdt.c to unconditionally include that file, and moves the
custom __early_init_dt_declare_initrd() definition away from
asm/memory.h

This cuts the number of objects rebuilds from 1920 down to 26, so a
factor 73 approximately.

Apologies for the long CC list, please let me know how you would go
about merging that and if another approach would be preferable, e.g:
introducing a CONFIG_ARCH_INITRD_BELOW_START_OK Kconfig option or
something like that.

In preparation for separating the definition of
__early_init_dt_declare_initrd() on ARM64 in order to cut the amount of
files that require a rebuild when CONFIG_BLK_DEV_INITRD value is
changed, introduce an empty asm-generic initrd.h file and update all
architectures but arm64 to make use of it.

* [PATCH 1/2] arch: Add asm-generic/initrd.h and make use of it for most architectures

  Cc: open list:MIPS, Alan Kao, open list:SUPERH,
	Benjamin Herrenschmidt, Will Deacon, Paul Mackerras,

	Richard Henderson, Matt Redfearn, Greg Kroah-Hartman, Ralf

In preparation for separating the definition of
__early_init_dt_declare_initrd() on ARM64 in order to cut the amount of
files that require a rebuild when CONFIG_BLK_DEV_INITRD value is
changed, introduce an empty asm-generic initrd.h file and update all
architectures but arm64 to make use of it.

In preparation for separating the definition of

files that require a rebuild when CONFIG_BLK_DEV_INITRD value is
changed, introduce an empty asm-generic initrd.h file and update all
architectures but arm64 to make use of it.

* [PATCH 1/2] arch: Add asm-generic/initrd.h and make use of it for most architectures
@ 2018-10-23 23:40   ` Florian Fainelli
  0 siblings, 0 replies; 27+ messages in thread
From: Florian Fainelli @ 2018-10-23 23:40 UTC (permalink / raw)
  To: linux-riscv

In preparation for separating the definition of
__early_init_dt_declare_initrd() on ARM64 in order to cut the amount of
files that require a rebuild when CONFIG_BLK_DEV_INITRD value is
changed, introduce an empty asm-generic initrd.h file and update all
architectures but arm64 to make use of it.

In preparation for separating the definition of
__early_init_dt_declare_initrd() on ARM64 in order to cut the amount of
files that require a rebuild when CONFIG_BLK_DEV_INITRD value is
changed, introduce an empty asm-generic initrd.h file and update all
architectures but arm64 to make use of it.

* [PATCH 1/2] arch: Add asm-generic/initrd.h and make use of it for most architectures
@ 2018-10-23 23:40   ` Florian Fainelli
  0 siblings, 0 replies; 27+ messages in thread
From: Florian Fainelli @ 2018-10-23 23:40 UTC (permalink / raw)
  To: linux-snps-arc

In preparation for separating the definition of
__early_init_dt_declare_initrd() on ARM64 in order to cut the amount of
files that require a rebuild when CONFIG_BLK_DEV_INITRD value is
changed, introduce an empty asm-generic initrd.h file and update all
architectures but arm64 to make use of it.

* [OpenRISC] [PATCH 1/2] arch: Add asm-generic/initrd.h and make use of it for most architectures
@ 2018-10-23 23:40   ` Florian Fainelli
  0 siblings, 0 replies; 27+ messages in thread
From: Florian Fainelli @ 2018-10-23 23:40 UTC (permalink / raw)
  To: openrisc

In preparation for separating the definition of
__early_init_dt_declare_initrd() on ARM64 in order to cut the amount of
files that require a rebuild when CONFIG_BLK_DEV_INITRD value is
changed, introduce an empty asm-generic initrd.h file and update all
architectures but arm64 to make use of it.

ARM64 is the only architecture that requires a re-definition of
__early_init_dt_declare_initrd(). Now that we added the infrastructure
in asm-generic to provide an asm/initrd.h file, properly break up that
definition from asm/memory.h and make use of that header in
drivers/of/fdt.c where this is used.

This significantly cuts the number of objects that need to be rebuilt on
ARM64 due to the repercusions of including asm/memory.h in several
places.

* [PATCH 2/2] arm64: Create asm/initrd.h

ARM64 is the only architecture that requires a re-definition of
__early_init_dt_declare_initrd(). Now that we added the infrastructure
in asm-generic to provide an asm/initrd.h file, properly break up that
definition from asm/memory.h and make use of that header in
drivers/of/fdt.c where this is used.

This significantly cuts the number of objects that need to be rebuilt on
ARM64 due to the repercusions of including asm/memory.h in several
places.

ARM64 is the only architecture that requires a re-definition of
__early_init_dt_declare_initrd(). Now that we added the infrastructure
in asm-generic to provide an asm/initrd.h file, properly break up that
definition from asm/memory.h and make use of that header in
drivers/of/fdt.c where this is used.

This significantly cuts the number of objects that need to be rebuilt on
ARM64 due to the repercusions of including asm/memory.h in several
places.
