Randy reports:
x86_64:
drivers/built-in.o: In function `xen_tpmfront_init':
xen-tpmfront.c:(.init.text+0x257c): undefined reference to `xenbus_register_frontend'
This is nicely fixed by selecting the XenBus frontend module.

This is a complete rewrite of the Xen TPM frontend driver, taking
advantage of a simplified frontend/backend interface and adding support
for cancellation and timeouts. The backend for this driver is provided
by a vTPM stub domain using the interface in Xen 4.3.

This is the driver for TPM chip from ST Microelectronics.
If you have a TPM security chip from STMicroelectronics working with
an I2C, in menuconfig or .config choose the tpm driver on
device --> tpm and activate the protocol of your choice before compiling
the kernel.
The driver will be accessible from within Linux.
Tested on linux x86/x64, beagleboard REV B & XM REV C and CHROMIUM OS

This patch adds a new device driver to support IBM virtual TPM
(vTPM) for PPC64. IBM vTPM is supported through the adjunct
partition with firmware release 740 or higher. With vTPM
support, each lpar is able to have its own vTPM without the
physical TPM hardware.
This driver provides TPM functionalities by communicating with
the vTPM adjunct partition through Hypervisor calls (Hcalls)
and Command/Response Queue (CRQ) commands.

This patch adds a driver to support Infineon's SLB 9635 TT 1.2 Soft I2C TPMs
which follow the TGC TIS 1.2 TPM specification[1] and Infineon's I2C Protocol
Stack Specification 0.20.
The I2C Protocol Stack Specification is a simple adaption of the LPC TIS
Protocol to the I2C Bus.
The I2C TPMs can be used when LPC Bus is not available (i.e. non x86
architectures like ARM).
The driver is based on the tpm_tis.c driver by Leendert van Dorn and Kyleen
Hall and has quite similar functionality.
Tested on Nvidia ARM Tegra2 Development Platform and Beagleboard (ARM OMAP)
Tested with the Trousers[2] TSS API Testsuite v 0.3 [3]
Compile-tested on x86 (32/64-bit)
Updates since version 2.1.4:
- included "Lock the I2C adapter for a sequence of requests", by Bryan Freed
- use __i2c_transfer instead of own implementation of unlocked i2c_transfer
- use struct dev_pm_ops for power management via SIMPLE_DEV_PM_OPS
Updates since version 2.1.3:
- use proper probing mechanism
* either add the tpm using I2C_BOARD_INFO to your board file or probe it
* during runtime e.g on BeagleBoard using :
* "echo tpm_i2c_infineon 0x20 > /sys/bus/i2c/devices/i2c-2/new_device"
- fix possible endless loop if hardware misbehaves
- improved return codes
- consistent spelling i2c/tpm -> I2C/TPM
- remove hardcoded sleep values and msleep usage
- removed debug statements
- added check for I2C functionality
- renaming to tpm_i2c_infineon
Updates since version 2.1.2:
- added sysfs entries for duration and timeouts
- updated to new tpm_do_selftest
Updates since version 2.1.0:
- improved error handling
- implemented workarounds needed by the tpm
- fixed typos

A previous commit removed its PNP dependency, that in fact wasn't
necessary, but also allowed it be built for other architectures not
supported by it. This then caused kernel oops on PPC based machines.
I'm placing a x86 dependency back correctly.

On m68k, I get:
drivers/char/tpm/tpm_atmel.h: In function ‘atmel_get_base_addr’:
drivers/char/tpm/tpm_atmel.h:129: error: implicit declaration of function ‘ioport_map’
drivers/char/tpm/tpm_atmel.h:129: warning: return makes pointer from integer without a cast
The code in tpm_atmel.h supports PPC64 (using the device tree and ioremap())
and "anything else" (using ioport_map()). However, ioportmap() is only
available on platforms that set HAS_IOPORT.
Although PC64 seems to have HAS_IOPORT, a "depends on HAS_IOPORT" should work,
but I think it's better to expose the special PPC64 handling explicit using
"depends on PPC64 || HAS_IOPORT".

This patch pushes the ACPI dependency into the device driver code
itself. Now, even without ACPI/PNP enabled, the device can be registered
using the TIS specified memory space. This will however result in the
lack of access to the BIOS event log, being the only implication of such
ACPI removal.

There is no "PNPACPI" driver interface as such. PNPACPI is an internal
backend of PNP, and drivers just use the generic PNP interface.
The drivers should depend on CONFIG_PNP, not CONFIG_PNPACPI.
tpm_nsc.c doesn't use PNP at all, so we can just remove the dependency
completely. It probably *should* use PNP to discover the device, but until it
does, there's no point in depending on PNP.

This patch includes support for the new Infineon Trusted Platform Module
SLB 9635 TT 1.2 and does further include ACPI-support for both chip
versions (SLD 9630 TT 1.1 and SLB9635 TT 1.2). Since the ioports and
configuration registers are not correctly set on some machines, the
configuration is now done via PNPACPI, which reads out the correct values
out of the DSDT-table. Note that you have to have CONFIG_PNP,
CONFIG_ACPI_BUS and CONFIG_PNPACPI enabled to run this driver (assuming
that mainboards including a TPM do have the need for ACPI anyway).

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].

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
