2017-07-28phy: add a NO-OP phy driverJean-Jacques Hiblot
This driver is used to stub PHY operations in a driver (USB, SATA). This is useful when the 'client' driver (USB, SATA, ...) uses the PHY framework and there is no actual PHY harwdare to drive. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>

solve issue on get_medium_size() function the detection of error is a simple test < 0 but for ARM platform, long is 32bits and 2GB = 0x80000000 is seen as error.

2017-07-28usb: xhci: Enable TT to support LS/FS devices behind a HS hubBin Meng
So far LS/FS devices directly attached to xHC root port can be successfully enumerated by xHCI driver, but if they are connected behind a hub, the enumeration process fails to address the device. It turns out xHCI driver still misses a part that in the device's input slot context, all Transaction Translator (TT) related fields are not programmed. The xHCI spec defines how to enable TT. Now LS/FS devices like USB keyboard/mouse can be enumerated behind a high speed hub. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2017-07-28usb: xhci: Implement update_hub_device() operationBin Meng
There is no way to know whether the attached device is a hub or not in advance before the device's descriptor is fetched. But once we know it's a high speed hub, per the xHCI spec, we need to tell xHC it's a hub device by initializing hub-related fields in the input slot context.

2017-07-28usb: xhci: Program 'route string' in the input slot contextBin Meng
xHCI spec says: the values of the 'route string' field shall be initialized by the first 'Address Device' command issued to a device slot, and shall not be modified by any other command. So far U-Boot does not program this field, and it does not prevent SS device directly attached to root port, or HS device behind an HS hub, from working, due to the fact that 'route string' is used by the xHC to target SS packets. But in order to enumerate devices behind an SS hub, this field must be programmed. With this commit and along with previous commits, now SS & HS devices attached to a USB 3.0 hub can be enumerated by U-Boot. As usual, this new feature is only available when DM is on.

A valid input slot context for a 'configure endpoint' command requires the 'Context Entries' field to be initialized to the index of the last valid endpoint context that is defined by the target configuration. We set up the 'Context Entries' field, but we forget to include the input slot context in the input control context 'Add Context flags' bitmap. So xHC will simply ignore input slot context and continue using its own which contains old information of the device.

2017-07-28usb: xhci: Initialize scratchpad buffer array and scratchpad buffersBin Meng
The scratchpad buffer array is used to define the locations of statically allocated memory pages that are available for the private use of the xHC. The xHCI spec explicitly mentions that system software shall allocate the scratchpad buffers before placing the xHC in to Run mode (Run/Stop (R/S) = ‘1’), however U-Boot is missing this part. This causes xHC on Intel platform does not respond the very first 'enable slot' command that is given to xHC and the 'enable slot' command completion event TRB is never generated and xHC seems to hang forever.
