Subject: [U-Boot] MPC8360 arbiter settings
Date: Mon, 22 Oct 2012 17:24:38 -0400	[thread overview]
Message-ID: <5085B996.7040806@ruggedcom.com> (raw)

Hello Anton and Dave,

I am seeing these MPC83xx arbiter settings in most boards except the
8360 ones. (Consistent with Ravi Chandran's recommendation at
http://www.freescale.com/files/training_presentation/TP_QUICC_SYSTEM_OPTIMIZATION.pdf).
Is there some reason these are not used for 8360? From some of my
experiments they seem to be beneficial.

/* Arbiter Configuration Register */
#define CONFIG_SYS_ACR_PIPE_DEP 3       /* Arbiter pipeline depth is 4 */
#define CONFIG_SYS_ACR_RPTCNT   3       /* Arbiter repeat count is 4 */
