From 5536aeb09b672e2541663fdc9370e2bc174dbae9 Mon Sep 17 00:00:00 2001 From: Shengzhou Liu Date: Fri, 13 Sep 2013 14:46:01 +0800 Subject: [PATCH] powerpc/eeprom: update MAX_NUM_PORTS to adapt non-256-bytes EEPROM Some boards use System EEPROM with 128-bytes instead of 256-bytes. Since we regard 256-bytes EEPROM as standard EEPROM with default value for MAX_NUM_PORTS. For those non-256-bytes EEPROM, we can redefine MAX_NUM_PORTS in board-specific file to override the default MAX_NUM_PORTS. This patch doesn't impact on previous existing boards.
