This patch set adds the ability to link device tree blobs into
vmlinux.
Patch 1 implements the changes to include/asm-generic/vmlinux.lds.h and
adds a generic rule for generating DTB objects to be linked vmlinux.
Patch 2 implements linking a DTB into an x86 image.
Patch 3-4 move {powerpc,microblaze}/boot/Makefile to use the dtc rule
in patch 1.
This patch set has been tested on x86.
Powerpc and Microblaze have been compile tested with and without patch
3 and 4 applied.
Changes from V1:
Documentation added for dtc command in Makefile.lib to
Documentation/kbuild/makefiles.txt
Separate DTB_ALIGNMENT define removed.
FORCE removed from dtc rule.
Removed hardcoded path to dts files from dtc command.
Moved %.dtb: %.dts rule to arch specific makefiles.
Patch for adding kernel command line option to pass in dtb_compat
string dropped from this set will be submitted seperately.
Changes from V2:
Rule to create assembly wrapper for blob changed to use Sam Ravnborgs
suggested implementation.
Rules in architecture specific Makefiles changed to use the cmd
function instead of the if_changed function.
Changes from V3:
Cosmetic fix of DTC quiet command
Dirk Brandewie (4):
of: Add support for linking device tree blobs into vmlinux

This patch adds support for linking device tree blob(s) into
vmlinux. Modifies asm-generic/vmlinux.lds.h to add linking
.dtb sections into vmlinux. To maintain compatiblity with the of/fdt
driver code platforms MUST copy the blob to a non-init memory location
before the kernel frees the .init.* sections in the image.
Modifies scripts/Makefile.lib to add a kbuild command to
compile DTS files to device tree blobs and a rule to create objects to
wrap the blobs for linking.
STRUCT_ALIGNMENT is defined in vmlinux.lds.h for use in the rule to
create wrapper objects for the dtb in Makefile.lib. The
STRUCT_ALIGN() macro in vmlinux.lds.h is modified to use the
STRUCT_ALIGNMENT definition.
The DTB's are placed on 32 byte boundries to allow parsing the blob
with driver/of/fdt.c during early boot without having to copy the blob
to get the structure alignment GCC expects.
A DTB is linked in by adding the DTB object to the list of objects to
be linked into vmlinux in the archtecture specific Makefile using
obj-y += foo.dtb.o

Hi,
you can add
Acked-by: Michal Marek <mmarek@suse.cz>
but I thing this series should go through the tip tree, as your primary
target seems to be x86 and patch 2/4 depends on the ce4100 code that is
only in tip.

If the two lines
+# device tree blob
+obj-$(CONFIG_X86_INTEL_CE) +=3D ce4100.dtb.o
are removed, patch 2/4 no longer depends on the ce4100 code.
The summary and description for that patch don't mention anything
about ce4100 anyway.

I'd like to take this through the dt tree. I'll drop the ce4100 hunk
when I merge it.

This patch adds linking device tree blob into vmlinux. DTB's are
added by adding the blob object name to list of objects to be linked
into the image.

Skipped for now; will pick up after ce4100 is in mainline since this
is a pretty low-risk change.

* [PATCH 0/4] V3 Add ability to link device blob(s) into vmlinux

From: Dirk Brandewie <dirk.brandewie@gmail.com>
This patch set adds the ability to link device tree blobs into
vmlinux.
Patch 1 implements the changes to include/asm-generic/vmlinux.lds.h and
adds a generic rule for generating DTB objects to be linked vmlinux.
Patch 2 implements linking a DTB into an x86 image.
Patch 3-4 move {powerpc,microblaze}/boot/Makefile to use the dtc rule
in patch 1.
This patch set has been tested on x86.
Powerpc and Microblaze have been compile tested with and without patch
3 and 4 applied.
Changes from V1:
Documentation added for dtc command in Makefile.lib to
Documentation/kbuild/makefiles.txt
Separate DTB_ALIGNMENT define removed.
FORCE removed from dtc rule.
Removed hardcoded path to dts files from dtc command.
Moved %.dtb: %.dts rule to arch specific makefiles.
Patch for adding kernel command line option to pass in dtb_compat
string dropped from this set will be submitted seperately.
Changes from V2:
Rule to create assembly wrapper for blob changed to use Sam Ravnborgs
suggested implementation.
Rules in architecture specific Makefiles changed to use the cmd
function instead of the if_changed function.
Dirk Brandewie (4):
of: Add support for linking device tree blobs into vmlinux
x86/of: Add building device tree blob(s) into image.
