First of all I think this should be more RFC.

Usb5744 & usb2244 are Microchip based usbhub and usb-2.0 based SD

I don't think this is going to be accepted by Marek to have device specific code
in generic code.
I did some grepping and I see that there is new CONFIG_USB_ONBOARD_HUB entry.
Don't understand why it is in common folder if this is pretty much device
specific. But there is a new UCLASS_USB_HUB class.
Venkatesh: it should be investigated more how it works.
Marek: IIRC you mentioned any support for companion/peer hubs.
How do you think it should be integrated to u-boot?
Thanks,
Michal
