These functions need to be moved to the main Makefile, since they are also needed for filogic targets. Example: https://github.com/openwrt-xiaomi/openwrt/commit/f10db8873eab15606ea5d5c03f9a616187df0a8e Function `uboot-fit` needs to be improved (made universal). Example: https://github.com/openwrt-xiaomi/openwrt/commit/f10db8873eab15606ea5d5c03f9a616187df0a8e

I suggest adding additional logging: ubi_prepare_rootfs=**echo "run ubi_prepare_rootfs" ;** if ubi check rootfs_data ; then **echo "volume rootfs_data already exists";** else if env exists rootfs_data_max ; then ubi create rootfs_data $rootfs_data_max dynamic || ubi create rootfs_data - dynamic ; else ubi create rootfs_data - dynamic ; fi ; fi

Maybe it's a chance to remove support for this device and add a new one `redmi,ax6s` instead. I remember `Redmi` is a standalone brand. It's not a series of `Xiaomi`.
