1.  Overview
============

The Infineon(R) TPM Bios Driver for memory present environments is a 
software module that allows the BIOS to communicate with an Infineon 
Technologies TPM device. This driver is referenced for 
a 32-bit PC architecture.

This module supports the following functions:
-  Initialisation of the communication channel with the TPM device.
-  Data transport between the HOST and the TPM.
-  Read the status information from the TPM device.

For additional information about the interface and the handling 
please use the TCPA-PC-Specific Implementation 
Specification v1.00 RC1 also.


2. System Requirements
======================

This driver serves a implementation reference for the 32-bit 
PC architecture.


3. Delivery/Installation
========================

- Readme.txt    (this file)
- TpmMpDrv.rom  (folder Seg32Drv) (TPM-Memory-Present-Driver-Image-File 32Bit segment version)
    On request:
    - TpmMpDrv.rom  (folder Seg16Drv) (TPM-Memory-Present-Driver-Image-File 16Bit segment version)
- DrvInOut.inc  (in folder IncDrv) Global interface constants/strucs for the TPMMADrv 
        and TPMMPDrv driver library
- RetCodes.inc  (in folder IncDrv) Return and error codes of the TPMMADrv 
        and TPMMPDrv driver library

4. Supported Standards
======================

- TCPA-PC-Specific Implementation Specification v1.00;v1.2.
- TCPA Main Specification v1.1b.
    (TCPA: Trusted Computing Platform Alliance)
        (http://www.trustedcomputing.org)
- IA-32 Architecture from Intel and AMD (with MMX-Support)
- System BIOS for IBM PCs, Compatibles, and EISA Computers


5. Known Issues
===============

This section is empty, but will be used in the further as new definition issues are raised.


6. Change History
=================

From version v0.30 to v0.50
- rework protocol error handling for invalid data (transport header) package transfer.

From version v0.50 to v0.60
- version alignment to TPMMADrv.

From version v0.60 to v0.70
- review and improve the timer handling concerning the clock granularity.

From version v0.70 to v0.80
- integrate the support for TPM v1.1 and v1.2 device id

From version v0.80 to v0.85/v0.90
- integrate new driver project for BigReal-Mode support

From version v0.90 to v0.95
- set interrupt selection and type to chip reset values (IRQSEL = 0x00, IRQTYPE = 0x02) 
  if it is disabled (Header-Offset 0x10 = 0xFF)
- change byte order for driver image signature (BYTE[2] to WORD)
- integrate usage of TPM configuration address header entry according to PC-Client v1.2
  (move from v1.1 location (Offset 0x0C) to the changed position in v1.2 (Offset 0x1C))
