Subject: [PATCH v4 07/10] arm64: kdump: Remove custom linux,elfcorehdr parsing
Date: Wed, 14 Jul 2021 14:50:17 +0200 [thread overview]
Message-ID: <65b6e3294cb84d50a6aab8503a9ebcf41445166d.1626266516.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1626266516.git.geert+renesas@glider.be>
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.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
