Hi all, drivers/core/device.c will call `device_free()` after xhci_register already frees the private device data. This causes a memory corruption and crash on my RPI4B. I believe the solution is to remove the free call in xhci_register ( https://github.com/u-boot/u-boot/blob/master/drivers/usb/host/xhci.c#L1421), thoughts? -Richard Habeeb
