We're running Android 9.0 with imx8mini, we want to disable system A/B feature, that's to say, we want the traditional Android upgrade method.
No boot_a, boot_b, system_a, system_b, etc, partions anymore, and for OTA update.zip, we want to upgrade under recovery mode.
How to disable this? I search config in the BoardConfig.mk, didn't find any clues.....
