Dear eija_flight,

During above initialization process of u-boot,
- Does it conduct a test to all board hardware listed?
No. In general, there is no testing performed. Minor exceptions from this rule exist, for example the RAM auto-sizing code also performas a minimal non-destructive memory test, but this is not strong enough to be called serious testing.
If you need real Power-On Self Tests (POST), then you must enable POST in your board configuration and configure it according to your needs.
- If above answer is yes, what method is used to do the test?
If you need such tests, then use the code in post/, see doc/README.POST
Best regards,
Wolfgang Denk
