I deliberately didn't do this, because fini_mmc_for_env() passes the value of mmc->part_num to call mmc_switch_part() in order to put things back the way they were. This fix would break that. Can you investigate why you're seeing the "MMC partition switch failed" message?

When running the "save" command several times on a mx6qsabresd we see: U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed Fix this by making mmc->part_num to be in sync with CONFIG_SYS_MMC_ENV_PART after the partition has been changed in mmc_switch_part(). After this fix, we no longer see the error after the "save" command on a mx6qsabresd. Also tested on a mx53loco.
