Hi~ My board gets stuck at the kernel stage during boot. I've referred to numerous related posts but failed to resolve the issue.
The boot file versions I use are OP-TEE 4.0, U-Boot 2023.10 and Linux 6.6.116.
The official device tree I referenced is stm32mp157f-ed1.
I have attached the boot logs, hardware schematic and device tree files. Please help analyze the root cause of the problem.

The log messages below are added by myself. RNG1 and IWDG1 can only be configured as secure peripherals in OP-TEE, so I believe these failure logs are not the cause of the boot stall.
