Sun, 22 Dec 2024 00:08:25 +0000

riscv: migrate to the generic rule for built-in DTBCommit 654102df2ac2 ("kbuild: add generic support for built-in bootDTBs") introduced generic support for built-in DTBs.Select GENERIC_BUILTIN_DTB when built-in DTB support is enabled.To keep consistency across architectures, this commit also renamesCONFIG_BUILTIN_DTB_SOURCE to CONFIG_BUILTIN_DTB_NAME.Signed-off-by: Masahiro Yamada Acked-by: Conor Dooley Link: https://lore.kernel.org/r/20241222000836.2578171-1-masahiroy@kernel.orgSigned-off-by: Alexandre Ghiti List of files: /linux-6.15/arch/riscv/Kbuild

Fri, 08 Apr 2022 10:09:13 +0000

RISC-V: Add purgatoryThis patch adds purgatory, the name and concept have been takenfrom kexec-tools. Purgatory runs between two kernels, and doverify sha256 hash to ensure the kernel to jump to is fine andhas not been corrupted after loading. Makefile is modified basedon x86 platform.Signed-off-by: Li Zhengyu Link: https://lore.kernel.org/r/20220408100914.150110-6-lizhengyu3@huawei.comSigned-off-by: Palmer Dabbelt List of files: /linux-6.15/arch/riscv/Kbuild

8212f898 - kbuild: use more subdir- for visiting subdirectories while cleaning

Wed, 13 Oct 2021 06:36:22 +0000

kbuild: use more subdir- for visiting subdirectories while cleaningDocumentation/kbuild/makefiles.rst suggests to use "archclean" forcleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement.Since commit d92cc4d51643 ("kbuild: require all architectures to havearch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick forall architectures. This can take advantage of the parallel option (-j)for "make clean".I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep"target no longer exists.Signed-off-by: Masahiro Yamada Reviewed-by: Kees Cook Acked-by: Geert Uytterhoeven Acked-by: Michael Ellerman (powerpc) List of files: /linux-6.15/arch/riscv/Kbuild

2d268251 - riscv: Allow device trees to be built into the kernel

Tue, 14 Apr 2020 04:43:24 +0000

riscv: Allow device trees to be built into the kernelSome systems don't provide a useful device tree to the kernel on boot.Chasing around bootloaders for these systems is a headache, so insteadle't's just keep a device tree table in the kernel, keyed by the SOC'sunique identifier, that contains the relevant DTB.This is only implemented for M mode right now. While we could implementthis via the SBI calls that allow access to these identifiers, we don'thave any systems that need this right now.Signed-off-by: Palmer Dabbelt List of files: /linux-6.15/arch/riscv/Kbuild
