Nit: the 3/3 in the Subject is incorrect as you are sending a single patch.

 diff --git a/configs/imx6ulz_smm_m2.config b/configs/imx6ulz_smm_m2.config

Please do as I suggested before:

1. PATCH 1/2: Send one patch that introduces
configs/imx6ulz_smm_m2.config and converts the existing
configs/imx6ulz_smm_m2b_defconfig and configs/imx6ulz_smm_m2_defconfig
to use it. Please write in the commit log that the reason for doing
this is to make maintainance easier, avoid duplication, and simplify
the introduction of new board variants in the future.

2. PATCH 2/2: Add M2D support using configs/imx6ulz_smm_m2.config.
