Wild speculation things
One I read was as others have mentioned, the whispers the mad king heard were Bran trying to communicate with him (and hence drove him mad). What I read said Bran was trying to warn the mad king of the white walkers and wights, telling him he must "burn them all", hence the mad king's love of fire and burning everyone
reply to speculation
quite possibly something like that... however it isn't likely to be Bran, more likely to have been bloodraven/three eyed crow since he is a Targaryen (or at least a Targaryen *******) like the Mad King
obviously these warnings, if the theory is true, didn't work and sent him mad
which would explain why the three eyed crow looked worried when Bran shouted out to the young version of his father in that tower scene as he already knows not to meddle with the past
I think after the Hodor incident last week Bran now knows not to meddle in the past too
