From bffac7aef54039dbe53dbf8bcbc9f8dbe78b8aa5 Mon Sep 17 00:00:00 2001 From: York Sun Date: Wed, 30 Apr 2014 14:43:46 -0700 Subject: [PATCH] powerpc/freescale: Change the return value of mac_read_from_eeprom() The return value has not been checked by its caller, until recent change of using generic board architecture. The error of this function is not critical enough to hang the system. Printing the warning message is enough to catch user's attention. U-boot should continue to boot to give user a chance to fix the EEPROM. Chaning the return value to 0 to avoid hanging in the board_init_r().
