A couple of commits have modified the am33xx/am437x ddr2/ddr3 initialization path to fix certain issues, but have had the side effect of causing L3 noc errors during initialization. The two commits are: 69b918 "am33xx,ddr3: fix ddr3 sdram configuration" fc46ba "arm: am437x: Enable hardware leveling for EMIF" The EMIF_REG_INITREF_DIS_MASK bit still needs to be set for all platforms. This delays initialization and refresh until a later stage. The 500us timer can be programmed for platforms that require it and for platforms that don't require it. It is currently hardcoded for 400MHz systems. For systems with a higher memory frequency this needs to be a larger value, and for systems with a lower memory frequency this can be a lower value. This can be considered a separate issue and corrected in a later commit. Signed-off-by: Russ Dill <Russ.Dill@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com> |
