It is allowed, but not recommended. You are running the risk that the
board vendor may make arbitrary changes to his board code, which may
work fine for him, but break your board. And you cannot even blame
him, because he probably is not even aware that this code gets used by
others who rely on it.
It is recommended to move such code to a common directory.

Please do not copy any files. Duplication of code is the worst that
can be done in such a szenario.

Before we go into details we should define a strategy. Can you please
be specific: which exact files are you talking about?
Then we can dicuss with the Freescale guys how to handle this
situation.
Best regards,
