[U-Boot] The post_list array order change

Just out of interest, what exactly do you test there?  Do you have any
way of measuring if the LEDs work or not?

As always, I would try to keep as much in common code as possible, so
I'd vote to prepend the entry in the global variable.  After all, it
will be CONFIG_SYS_POST_DIAG protected, correct?

But then again, the order of the tests should generally be from the
simple to the more complex, so I would really need to know what your
test does.  I.e. will a failure in the test be a general POST failure?
Can it run if already available tests will fail?

Actually, looking at the current order, it is not very clear to me if
this is "optimal" in the light of the thoughts laid out in the previous
paragraph.

It seems I have to think about this a little more.  Does anybody else
have an idea if the current ordering is in any way sensible?

Cheers
