[PATCH v3 1/5] target/microblaze: Define TCG_GUEST_DEFAULT_MO


From: Richard Henderson
Subject: [PATCH v3 1/5] target/microblaze: Define TCG_GUEST_DEFAULT_MO
Date: Mon, 19 Jun 2023 16:23:29 +0200

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.
