[PATCH] tpm: Support for Infineon TPM

This patch provides a new device driver for the Infineon SLD 9630 TT Trusted
Platform Module (TPM 1.1b) [1] which is embedded on Intel- mainboards or in
HP/ Fujitsu-Siemens / Toshiba-Notebooks.  A nearly complete list where this
module is integrated in can be found in [2].

This kernel module acts as a communication gateway between the linux kernel
and the hardware chip and fits the TPM-specific interfaces created by IBM in
drivers/char/tpm/tpm.h

Further information about this module and a list of succesfully tested and
therefore supported hardware can be found at our project page [3].
