Subject: [PATCH v3 13/17] target/microblaze: Introduce mo_endian() helper
Date: Fri,  8 Nov 2024 15:43:13 +0000	[thread overview]
Message-ID: <20241108154317.12129-14-philmd@linaro.org> (raw)
In-Reply-To: <20241108154317.12129-1-philmd@linaro.org>

mo_endian() returns the target endianness, currently static.
