The rule in U-Boot when generating output is to print a message
before you start an action, and then either print an OK or an error
message. The reason for this is debug support: if neither an OK nor
an error comes you know that the test somehow crashed.
Here this principle is violated as image_check_magic() and
image_check_hcrc() will run without being announced.
Please move the output so we get a message printed before starting to
perform the actual tests.
Best regards,
Wolfgang Denk
