dm: tpm: Drop CONFIG_DM_TPM

2015-10-23T15:42:28+00:00

Now that all TPM drivers use driver model, we can drop the special driver
model CONFIG option.

dm: tpm: Move tpm_tis_i2c to tpm_i2c_infineon

2015-10-23T15:42:28+00:00

As there is no TCG specification or recommendation for i2c TPM 1.2,
move tpm_tis_i2c driver to tpm_i2c_infineon. Other tpm vendors like Atmel
or STMicroelectronics may have a different transport protocol for i2c.

dm: tpm: Add a uclass for Trusted Platform Modules

2015-08-31T13:57:28+00:00

Add a new uclass for TPMs which uses almost the same TIS (TPM Interface
Specification) as is currently implemented. Since init() is handled by the
normal driver model probe() method, we don't need to implement that. Also
rename the transfer method to xfer() which is a less clumbsy name.

Once all drivers and users are converted to driver model we can remove the
old code.

tpm: Move the I2C TPM code into one file

2015-08-31T13:57:27+00:00

The current Infineon I2C TPM driver is written in two parts, intended to
support use with other I2C devices. However we don't have any users and the
Atmel I2C TPM device does not use this file.

We should simplify this and remove the unused abstration. As a first step,
move the code into one file.

Also the name tpm_private.h suggests that the header file is generic to all
TPMs but it is not. Rename it indicate that it relates only to this driver

sandbox: tpm: Add TPM emulation

2014-01-09T00:25:12+00:00

Add a simple TPM emulator for sandbox. It only supports a small subset of
TPM operations. However, these are enough to perform common tasks.

Note this is an initial commit to get this working, but it could use
cleaning up (for example constants instead of open-coded values).

tpm: Reorganize the I2C TPM driver

2013-06-03T08:31:23+00:00

This patch does a similar code reogranzation from
  http://patchwork.ozlabs.org/patch/132179/
which is based on an old version of code (fdt support and bus selection
still not in). It merges this tidy-up on top of the recent code. It does
not make any logical change.

tpm.c implements the interface defined in tpm.h based on underlying
LPC or I2C TPM driver. tpm.c and the underlying driver communicate
throught tpm_private.h.

Note: Merging the LPC driver with tpm.c is left to future patches.
