Subject: [PATCH 3/3] arm64: kdump: Remove custom linux,elfcorehdr parsing
Date: Tue, 15 Jun 2021 20:17:27 +0200 [thread overview]
Message-ID: <169c69d085fc235592208d4669785a3f94248f28.1623780059.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1623780059.git.geert+renesas@glider.be>
Remove the architecture-specific code for handling 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.
