Add logic to flush all UART transmit buffers if there is a
config change from Reset(), SetAttributes() or SetControl().
Use a timeout in the flush operation, so the system can
continue to boot if the transmit buffers can not be
flushed for any reason.
This change prevents lost characters on serial debug logs
and serial consoles when a config change is made. It also
prevents a UART from getting into a bad state or reporting
error status due to characters being transmitted at the same
time registers are updated with new communications settings.

This commit adds code to restart the ATA packets that failed due to the
CRC error or other link condition. For sync transfers the code will try
to get the command working for up to 5 times. For async transfers, the
command will be retried until the timeout value timeout specified by the
requester is reached. For sync case the count of 5 retries has been
chosen arbitrarily and if needed can be increased or decreased.

AHCI driver used to poll D2H register type to determine whether the FIS
has been received. This caused a problem of long timeouts when the link
got a CRC error and the FIS never arrives. To fix this this change
switches AHCI driver to poll the IS register which will signal both the
reception of FIS and the occurrence of error.

With some super-speed USB mass storage devices it has been observed
that a USB transaction error may occur when attempting the set the
device address during enumeration.
According the the xHCI specification (section 4.6.5) ...
"A USB Transaction ErrorCompletion Code for an Address Device Command
may be due to a Stall response from a device. Software should issue a
Disable Slot Commandfor the Device Slot then an Enable Slot Command
to recover from this error."
To fix this, retry the device slot initialization if it fails due to a
device error.
Change was verified using a superspeed mass storage device that was
occasionally failing to enumerate in UEFI. With this change this failure
to enumerate was resolved. This failure was also only seen in UEFI and not
in the OS.

Currently UsbDevContext is not cleaned up if USB slot initialization is
failed, the wrong context data will affect next USB devices and
the USB devices can not be enumerated.
Need to disable slot if USB slot initialization is failed.
Below test cases are passed on UpXtreme:
a. USB 3.0 thumb drives can be recognized in UEFI shell
b. SUT can boot to Puppylinux from USB3.0 mass storage,
the storage can be recognized in linux
c. Plug in a USB keyboard (hot plug) and enumeration is OK
in UEFI shell and linux
d. Plug in a USB mouse(hot plug) and enumeration is OK in linux.

Remove this private macro definition, and adopt PCI_MAX_BAR from

remain unchanged (the standard PCI_MAX_BAR macro expands to 0x0006).
"NonDiscoverablePciDeviceIo.h" gets the definition of PCI_MAX_BAR via its

The commit will avoid unmapping the same resource in error handling logic
for function BuildAdmaDescTable() and SdMmcCreateTrb().
For the error handling in BuildAdmaDescTable():
The error is directly related with the corresponding Map() operation
(mapped address beyond 4G, which is not supported in ADMA), so the Unmap()
operation is done in the error handling logic, and then setting
'Trb->AdmaMap' to NULL to avoid double Unmap.
For the error handling in SdMmcCreateTrb():
The error is not directly related with the corresponding Map() operation,
so the commit will update the code to left SdMmcFreeTrb() for the Unmap
operation to avoid double Unmap.

The endpoint selected by the driver needs to not
only be an interrupt type, but have direction IN
as required to set up an asynchronous interrupt transfer.
Currently, the driver assumes that the first INT endpoint
will be of type IN, but that is not true of all devices,
and will silently fail on devices which have the OUT endpoint
before the IN. Adjust the endpoint selection loop to explictly
check for direction IN.

the notification won't be sent to avoid changing old behavior.

When a packet is queued/completed for the asynchronous IO queue, the logic
to roll over to the front of the queue doesn't account for actual size of
the IO Submission/Completion queue.
This causes a device to hang due to doorbell being outside of visible
queue. An example would be if an NVMe drive only supported a queue size of
128 while the driver supports 256.

Whenever a PCI device is discovered, PCI bus calls the
EDKII_DEVICE_SECURITY_PROTOCOL to authenticate it.
If the function returns success, the PCI bus allocates
the resource and installs the PCI_IO for the device.
If the function returns fail, the PCI bus skips the device.
It is similar to EFI_SECURITY_ARCH_PROTOCOL, which
is used to verify an EFI image.
