MdeModulePkg: Add UFS (Universal Flash Storage) Stack
It includes 4 drivers: 1. UfsPassThruDxe, which is a UEFI driver and consumes EFI_UFS_HOST_CONTROLLER_PROTOCOL and produces EFI_EXT_SCSI_PASS_THRU_PROTOCOL 2. UfsPciHcDxe, which is specific for pci-based UFS HC implementation and is a UEFI driver to produce EFI_UFS_HOST_CONTROLLER_PROTOCOL. 3. UfsBlockIoPei, which is a PEI driver and consumes EFI_UFS_HOST_CONTROLLER_PPI and produces EFI_PEI_VIRTUAL_BLOCK_IO_PPI. 4. UfsPciHcPei, which is specific for pci-based UFS HC implementation and is a PEI driver to produce EFI_UFS_HOST_CONTROLLER_PPI.

/**

Tests to see if this driver supports a given controller. If a child device is provided,
|
||||
it further tests to see if this driver supports creating a handle for the specified child device.
|
||||
|
||||
This function checks to see if the driver specified by This supports the device specified by
|
||||
ControllerHandle. Drivers will typically use the device path attached to
|
||||
ControllerHandle and/or the services from the bus I/O abstraction attached to
|
||||
ControllerHandle to determine if the driver supports ControllerHandle. This function
|
||||
may be called many times during platform initialization. In order to reduce boot times, the tests
|
||||
performed by this function must be very small, and take as little time as possible to execute. This
|
||||
function must not change the state of any hardware devices, and this function must be aware that the
|
||||
device specified by ControllerHandle may already be managed by the same driver or a
|
||||
different driver. This function must match its calls to AllocatePages() with FreePages(),
|
||||
AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
|
||||
Since ControllerHandle may have been previously started by the same driver, if a protocol is
|
||||
already in the opened state, then it must not be closed with CloseProtocol(). This is required
|
||||
to guarantee the state of ControllerHandle is not modified by this function.
|
||||
|
||||
@param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
|
||||
@param[in] ControllerHandle The handle of the controller to test. This handle
|
||||
must support a protocol interface that supplies
|
||||
an I/O abstraction to the driver.
|
||||
@param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This
|
||||
parameter is ignored by device drivers, and is optional for bus
|
||||
drivers. For bus drivers, if this parameter is not NULL, then
|
||||
the bus driver must determine if the bus controller specified
|
||||
by ControllerHandle and the child controller specified
|
||||
by RemainingDevicePath are both supported by this
|
||||
bus driver.
|
||||
|
||||
@retval EFI_SUCCESS The device specified by ControllerHandle and
|

RemainingDevicePath is supported by the driver specified by This.

@retval EFI_ALREADY_STARTED The device specified by ControllerHandle and

RemainingDevicePath is already being managed by the driver
|

specified by This.

@retval EFI_ACCESS_DENIED The device specified by ControllerHandle and

driver or an application that requires exclusive access.

Currently not implemented.

This function checks to see if the driver specified by This supports the device specified by

ControllerHandle and/or the services from the bus I/O abstraction attached to
