LS1046, How to load Linux kernel without using SEC Firmware? (HELP!)

Hi, experts

I am trying to port ATF/Uboot/linux using the ls1046 CPU custom board that does not support secure mode. I checked that it boots up to ATF and Uboot, but when I download the kernel as tftp and try to boot, the following error occurs.

Verifying Hash Integrity ... OK

It is presumed to be a problem caused by not using SEC, and when I set the CONFIG_ARMV8_SEC_FIRMWARE_SUPPORT item in the Uboot config item to n, the lsdk2108_yocto_tiny_LS_arm64.itb file loaded as tftp is not recognized with an error "wrong Image Format for bootm command" when booting.
If the SEC Firmware is not supported, does the itb image not load? So, what linux kernel image should I use when not using SEC Firmware?

Please, Help me!

When CONFIG_ARMV8_SEC_FIRMWARE_SUPPORT=n and INCLUDE_FIT=y are applied, it loads normally.
