ENGR00163697 - FEC : Adjust MX53 Network stream throughput.
- When the system is very busy(such as play 1080p streaming in local) the WIFI & FEC performance were very low. - Enable the patch in uboot for WIFI and FEC performance: If WIFI connect to PORT2, enable the config: CONFIG_ADJUST_WIFI_FEC_PERFORMANCE CONFIG_WIFI_SDHC_PORT2 If WIFI connect to port3, enable the config: CONFIG_ADJUST_WIFI_FEC_PERFORMANCE CONFIG_WIFI_SDHC_PORT3 - The solution of the patch: I. Changing M4IF dynamic jump value to zero, which can guarantee FEC the high rate of accessing bus. II. Increase Master 4 priority for FEC. Increase Master 2 and AHBMAX priority for WIFI. - Test result: i.MX53 FEC bandwidth (1080p streaming playback in local): 47.1 Mbits/sec. Signed-off-by: Fugang Duan <B38611@freescale.com>
