Date: Mon, 22 Oct 2012 17:24:38 -0400 [thread overview]

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 */
