From 07815eb9f3f742237085e3eda947e095926212b0 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Thu, 27 Aug 2015 19:37:12 +0200 Subject: omap-common: Common serial and usbethaddr functions based on die id Now that we have a common prototype to grab the omap die id, functions to figure out a serial number and usb ethernet address can use it directly. Those also get an omap_die_id prefix for better consistency.
