I did more debugging and something is really weird though. When the
link address is changed to 0x800000, when stepping through the kernel,
I actually got the kernel boot successfully. However I let the kernel
run through it would just crash. After crash the BDI2000 shows it
stopped at __delay().

I also changed the link address to 0x4000000. During the function
of_scan_flat_dt(early_init_dt_scan_chosen, NULL) called in
early_init_devtree(), gdb shows the program (i.e. kernel) received a
signal SIGSTOP.

Why would the kernel crash during that time? of_scan_flat_dt() doesn't
seem to be the cause of SIGSTOP. What would that be then?

Thanks,
