Subject: [PATCH 10/10] target/microblaze: convert gdbstub to new helper
Date: Wed, 19 Mar 2025 18:22:55 +0000	[thread overview]
Message-ID: <20250319182255.3096731-11-alex.bennee@linaro.org> (raw)
In-Reply-To: <20250319182255.3096731-1-alex.bennee@linaro.org>

This is a pretty simple conversion which will be trivial to update
once TARGET_BIGENDIAN is replaced with a helper function.
