It is better to post at the bottom that the top, for mailing lists.
I think PCI XHCI has some problems. I'm not sure of its status.
MMC seems to work well on Minnowboard Max (baytrail) but I am not sure about braswell. Is it perhaps a slightly different chip?

For PCI XHCI, i see controller usb and root hub, but cannot reset port:
portstatus 711, change 0, 5 Gb/s STAT_C_CONNECTION = 0 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 0 portstatus 711, change 10, 5 Gb/s STAT_C_CONNECTION = 0 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 0 portstatus 711, change 10, 5 Gb/s STAT_C_CONNECTION = 0 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 0 portstatus 711, change 10, 5 Gb/s STAT_C_CONNECTION = 0 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 0 portstatus 711, change 10, 5 Gb/s STAT_C_CONNECTION = 0 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 0 Cannot enable port 10 after 5 retries, disabling port. Maybe the USB cable is bad? cannot reset port 10!?
do you have an idea,why reset port is break down ?
No I am not sure. It could possibly be a driver problem, or perhaps the port is not enabled in the FSP config?
For MMC, braswell n3160 is dedicated for embedded iot, maybe for security.
Do you mean that you cannot use MMC on this chip?
