From f9539a9caa12195870cfc3b0cf6150755aeb2e52 Mon Sep 17 00:00:00 2001 From: Shaohui Xie Date: Mon, 25 Mar 2013 07:40:18 +0000 Subject: [PATCH] powerpc/p2041: fix serdes reference clock frequency display for PC board PC board has different serdes clock setting with PB board, it uses same serdes frequency setting on bank2 as on bank1. PC board can be distingushed from PB board by checking CPLD version, if running on PC board, then fix the serdes reference clock frequency of bank2.
