Reading the manual more carefully discovers a different logic for the
DCD 'check' command. They use the term "until". In order to get the

This makes the imxcfg files more readable and also makes it possible to
share more assignments between machines that just differ by the used

more easily allows to see that the RAM config differs more than probably
necessary.)

This change is intended to have no effect on the built artifacts.
