Subject: [PATCH v4 1/5] RISC-V: Add EM_RISCV to kexec UAPI header
Date: Mon, 19 Apr 2021 03:55:35 +0300
Message-ID: <20210419005539.22729-2-mick@ics.forth.gr> (raw)
In-Reply-To: <20210419005539.22729-1-mick@ics.forth.gr>

Add RISC-V to the list of supported kexec architectures, we need to
add the definition early-on so that later patches can use it.

EM_RISCV is 243 as per ELF psABI specification here:
https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md
