It's not critical, but I'd have liked to understand this, so I can check if it's perhaps a barebox bug. > Currently the workaround I am using is just to set the size of the kernel partition to match the exact size of the "Image" file. > > The other issue I am facing is that Kernel seems stuck on cpu_do_idle and there is no login prompt from the kernel.

Nice. Didn't know about this option.

Normally, I'd try again with pd_ignore_unused clk_ignore_unused in the kernel arguments, but I think you define no clocks or power domains yet in the DT? You can try again with kernel command line option initcall_debug and see what the initcall is that is getting stuck. If nothing helps, maybe attach a hardware debugger?
