The new Rom_session::update function can be used to request the update of an existing ROM dataspace. If the new data fits into the existing dataspace, a subsequent call of 'dataspace' can be omitted. This way, ROM dataspace updates don't suffer from page-fault-handling costs that would occur when replacing the dataspace with each update.
