Subject: [PATCH v2 06/20] filetype: detect RISC-V Linux kernel image
Date: Tue, 16 Mar 2021 09:04:51 +0100	[thread overview]
Message-ID: <20210316080505.19361-7-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210316080505.19361-1-a.fatoum@pengutronix.de>

We still have no boot support for RISC-V, take the first step by
enabling barebox to detect a RISC-V Linux kernel image. The header
format is aligned with that of arm64.
