[PATCH v4 07/10] arm64: kdump: Remove custom linux,elfcorehdr parsing
From: Geert Uytterhoeven <geert+renesas@glider.be>
Date: 2021-07-14 12:51:57
Also in:
kexec, linux-arm-kernel, linux-devicetree, linux-renesas-soc, linux-riscv, lkml
Subsystem:
arm64 port (aarch64 architecture), the rest · Maintainers:
Catalin Marinas, Will Deacon, Linus Torvalds
Remove the architecture-specific code for parsing the "linux,elfcorehdr" property under the "/chosen" node in DT, as the platform-agnostic handling in the FDT core code already takes care of this.
