Subject: [PATCH v4 09/16] target/microblaze: Introduce mo_endian() helper
Date: Thu,  6 Feb 2025 12:33:14 +0100	[thread overview]
Message-ID: <20250206113321.94906-10-philmd@linaro.org> (raw)
In-Reply-To: <20250206113321.94906-1-philmd@linaro.org>

mo_endian() returns the target endianness, currently static.
