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.

tpm: Reorganize the I2C TPM driver 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.
