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 you need such tests, then use the code in post/, see doc/README.POST
