When I use Orange Pi Prime to do some heavy compliation tasks, the gcc compiler sometimes mysteriously segfaults, and memtester catches memory error. As the lima-memtester cannot support H5 (Mali-450 GPU equipped), there's no really reliable way to detect DRAM stability except try and error.

Lower the DDR frequency to 624MHz seems to solved the issue.

I'm not sure, since ddr can be keyrole IP during relocation and falcon mode(which I'm trying) but we can make sure the ddr test in uboot atleast?

thanks!
