From 52d848695c36d2b6ce688d1403653653e82583b4 Mon Sep 17 00:00:00 2001 From: Igor Grinberg Date: Wed, 5 Nov 2014 13:29:54 +0200 Subject: am335x: make get_board_rev() function weak Current get_board_rev() function returns a hard coded value which is obviously incorrect for the majority of boards. Allow boards to provide a correct implementation by making this function weak. In addition open code the trivial and useless BOARD_REV_ID define and adjust the comment.
