2016-07-19arm64: localise Image objcopy flagsMark Rutland1-0/+2
We currently define OBJCOPYFLAGS in the top-level arm64 Makefile, and thus these flags will be passed to all uses of objcopy, kernel-wide, for which they are not explicitly overridden. The flags we set are intended for converting vmlinux (and ELF) into Image (a raw binary), and thus the flags chosen are problematic for some other uses which do not expect a raw binary result, e.g. the upcoming lkdtm rodata test: http://www.openwall.com/lists/kernel-hardening/2016/06/08/2 This patch localises the objcopy flags such that they are only used for the vmlinux -> Image conversion.

2016-02-19arm64: kbuild: make "make install" not depend on vmlinuxMasahiro Yamada1-2/+2
For the same reason as commit 19514fc665ff ("arm, kbuild: make "make install" not depend on vmlinux"), the install targets should never trigger the rebuild of the kernel. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
2015-07-27arm64: enable more compressed Image formatsOlof Johansson1-0/+12
Plumb up Makefile arguments for the already supported formats in the kbuild system: lz4, bzip2, lzma, and lzo. Note that just as with Image.gz, these images are not self-decompressing and the booting firmware still needs to handle decompression before launching the kernel image.

2012-12-03arm64: use new common dtc ruleStephen Warren1-5/+0
The current rules have the .dtb files build in a different directory from the .dts files. This patch changes arm64 to use the generic dtb rule which builds .dtb files in the same directory as the source .dts. This requires moving parts of arch/arm64/boot/Makefile into newly created arch/arm64/boot/dts/Makefile, and updating arch/arm64/Makefile to call the new Makefile.
