Introduce generic TPM support in u-boot TPM (Trusted Platform Module) is an integrated circuit and software platform that provides computer manufacturers with the core components of a subsystem used to assure authenticity, integrity and confidentiality. This driver supports version 1.2 of the TCG (Trusted Computing Group) specifications. The TCG specification defines several so called localities in a TPM chip, to be controlled by different software layers. When used on a typical x86 platform during the firmware phase, only locality 0 can be accessed by the CPU, so this driver even while supporting the locality concept presumes that only locality zero is used. This implementation is loosely based on the article "Writing a TPM Device Driver" published on http://ptgmedia.pearsoncmg.com Compiling this driver with DEBUG defined will generate trace of all accesses to TMP registers. This driver has been tested and is being used in three different functional ChromeOS machines (Pinetrail and Sandy Bridge Intel chipsets) all using the same Infineon SLB 9635 TT 1.2 device. A u-boot cli command allowing access to the TPM was also implemented and is being submitted as a second patch.

dm: tpm: Drop CONFIG_DM_TPM Now that all TPM drivers use driver model, we can drop the special driver model CONFIG option. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Christophe Ricard<christophe-h.ricard@st.com>

dm: tpm: Add a uclass for Trusted Platform Modules 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.

Other tpm vendors like Atmel or STMicroelectronics may have a different transport protocol for i2c.

sandbox: tpm: Add TPM emulation 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).
