From 2da87ab3539264af595d8cb2d6dc7e087f1f1ca7 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Thu, 27 Aug 2015 19:37:14 +0200 Subject: omap-common: Common get_board_serial function to pass serial through ATAG Since there is a common function to grab the serial number from the die id bits, it makes sense have one to parse that serial number and feed it to the serial ATAG.
