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 ?
For MMC, braswell n3160 is dedicated for embedded iot, maybe for security.
