I'm having problems when using Btrfs for my rootfs. I'm generatig my image with Yocto and as far as I know U-Boot support it. My zImage and my dts are located at boot and I already enabled Btrfs configs on menuconfig.
At boot process I'm getting: [ 3.454910] Btrfs loaded, crc32c=crc32c-generic, debug=on, assert=on, integrity-checker=on, ref-verify=on, zoned=no, fsverity=no

Have you ever faced something like that?
