niruiyu c86b273d90 Grub4Dos copies the BPB of the first partition to the MBR. If the DriverBindingStart() of the Fat driver gets run before that of Partition driver only the first partition can be recognized. 
Let the driver binding version of Partition driver be higher than that of Fat driver to make sure the DriverBindingStart() of the Partition driver gets run before that of Fat driver so that all the partitions can be recognized.

vanjeff 9be2900668 1. updated "the Bus Driver that creates all of its child handles on the first call to Start()" not to create any child handle if RemainingDeviepath is the End of Device Path Node, per UEFI 2.3. 
The others changes include:
a. Check RemainingDevicePath at beginning of Supported(), make sure it has been verified before Start() is called.
b. Check IO protocol firstly rather than EfiDevicePathProtocolGuid, reduce the times entering into Start() function because EfiDevicePathProtocolGuid existed on most of handle.

2. roll back serial drivers not to create child device, if the device speicifed by remainingdevicepath cannot find in the created devices list.

eric_tian 15a865075c Roll back the change in Partition driver. currently we enhance the EHCI driver to guarantee that the EHCI controller get attached to the EHCI controller before the UHCI driver attaches to the UHCI controller. This way can avoid the case happen that UHCI sees the disconnect and EHCI sees the connect event due to the control transfer in shared port. It may cause Partition.Start to be interrupted by Partition.Stop.

eric_tian c8148ea20d if Usb mass storage interface returns EFI_DEVICE_ERROR, we should jump out the loop which is used to determine if the current block device supports GPT/Torito/MBR in Partition driver. This way can avoid Partition.start is interrupted by itself Partition.stop().
