Re: [coreboot] How to check if DRAM init is OK?
How about MemTest86? See this link http://www.coreboot.org/Memtest86, I never use it before.

Re: [coreboot] How to check if DRAM init is OK?
it's an ARM. There was a primitive memory test in the early days of our ARM ports that might be useful. It was simple but it caught our problems.
