(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 */ -- Michael Barkowski Software Engineer, ROX Platform Infrastructure RuggedCom Software Engineering, Concord, Ontario
