[PATCH v4 07/10] arm64: kdump: Remove custom linux,elfcorehdr parsing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
