From 66412c6371cfd6e056679abedea7d6fafe6a0422 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Fri, 18 Feb 2011 05:40:54 -0600 Subject: powerpc/85xx: Change timebase divisor to be defined per processor Introduce new CONFIG_SYS_FSL_TBCLK_DIV on 85xx platforms because different SoCs have different divisor amounts. All the PQ3 parts are /8, the P4080/P4080 is /16, and P2040/P3041/P5020 are /32.
