Andrzej,
This patch looks similar to what was done recently for overo.
Please add a comment in the code to the setting of the pullup.
Please also add a comment to commit log explaining why this
needs to change, just saying it is wrong is not enough of
an explanation.  In the case of overo, the problem that was
fixed was random hangs when the serial wasn't connected.

Please also check is any new at91 boards were added since
you first submitted this patch.

Tom
