Subject: [PULL 16/22] target/microblaze: Define TCG_GUEST_DEFAULT_MO
Date: Mon, 26 Jun 2023 17:39:39 +0200	[thread overview]
Message-ID: <20230626153945.76180-17-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230626153945.76180-1-richard.henderson@linaro.org>

The microblaze architecture does not reorder instructions.
While there is an MBAR wait-for-data-access instruction,
this concerns synchronizing with DMA.

This should have been defined when enabling MTTCG.

Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org>

Fixes: d449561b130 ("configure: microblaze: Enable mttcg")
