From 89e536a190f90d038bae7905a0c582cb7089b739 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 28 Sep 2007 22:42:16 -0700 Subject: ax88796: add 93cx6 eeprom support Hook up the 93cx6 eeprom code to the ax88796 driver and modify the ax88796 driver to read out the mac address from the eeprom. We need this for the ax88796 on certain SuperH boards. The pin configuration used to connect the eeprom to the ax88796 on these boards is the same as pointed out by the ax88796 datasheet, so we can probably reuse this code for multiple platforms in the future.
