[Patch 0/3] QuarkPlatformPkg/Tpm12DeviceLibAtmelI2c: Fix TPM issues

[Michael Kinney]

Fix several issues with the Atmel I2C TPM library in the QuarkPlatformPkg.
This includes GCC build failures, a corner case for an incorrect output
buffer size, and a TPM detection failure due to increased error checking
in the Tpm12CommandLib.

[Patch 1/3] QuarkPlatformPkg/Tpm12DeviceLibAtmelI2c: Remove PP Check

[Michael Kinney]

https://bugzilla.tianocore.org/show_bug.cgi?id=337

The Tpm12CommandLib in the SecurityPkg was updated to check
the returnCode in the response packet in the following
commit:

https://github.com/tianocore/edk2/commit/950a3bc788b5b101729b26aed3ff75fd2a64a570

The Tpm12DeviceLibAtmelI2C uses the Tpm12PhysicalPresence()
function from the Tpm12CommandLib to verify that the I2C device
is responding to TPM command packets.  However, at this point
the TPM device has not been started, and the TPM properly
responds with an error in the returnCode field of the response
packet.  Before the commit above, the check worked, but the
additional error checking in the commit above now returns an
error and an Atmel I2C is returned as not present.

The fix is to remove the call to the Tpm12PhysicalPresence()
API in the Tpm12CommandLib from the Tpm12RequestUseTpm() API.
The Atmel I2C TPM device is detected if a byte can be read
from the slave address assigned to the Atmel I2C device.
When the startup command is sent to the TPM later, the
command and response packet processing will be verified, and
if the I2C device is not an Atmel TPM, it will be detected
at that point.

[Patch 2/3] QuarkPlatformPkg/Tpm12DeviceLibAtmelI2c: Fix SubmitCommand() out size

[Michael Kinney]

https://bugzilla.tianocore.org/show_bug.cgi?id=336

When the Tpm12SubmitCommand() detects a response packet that
is the same size as a TPM_RSP_COMMAND_HDR, it returns
EFI_SUCCESS without reading any additional response packet
information from the TPM.  In that case, the return parameter
OutputParameterBlockSize is not be updated, so the size of
that OutputParameterBlock returned is the value passed in which
could be larger than what is actually returned from the TPM.

Set the OutputParameterBlockSize to the size of the
TPM_RSP_COMMAND_HDR when this specific condition is detected.
