Subject: [PATCH 2/9] target/microblaze: Split out mb_transaction_failed_internal
Date: Wed, 12 Feb 2025 14:01:48 -0800	[thread overview]
Message-ID: <20250212220155.1147144-3-richard.henderson@linaro.org> (raw)
In-Reply-To: <20250212220155.1147144-1-richard.henderson@linaro.org>

Use an explicit 64-bit type for the address to store in EAR.
