drivers/tpm/tpm_tis_sandbox.c: Fix uninitialized variable use

2016-04-15T14:14:37+00:00

In rollback_space_kernel we were not initializing the reserved fields
which should be for safety sake, and doing memset here means we don't
need to set the version field specifically either.

lib/crc8: Add crc start value

2016-04-12T00:48:26+00:00

To make the usage of this function more flexible, lets add the CRC start
value as parameter to this function. This way it can be used by other
functions requiring different start values than 0 as well.

For non-zero CRC start values to work, I've reworked the function a bit.
The new implementation is copied from the Linux version in
drivers/i2c/i2c-core.c / i2c_smbus_pec(). Which supports non-zero
CRC stating values.

I've double-checked that the results for zero starting values are
identical to the results from the original version of this function.

tpm: st33zp24: Add tpm st33zp24 spi support

2016-01-29T04:01:22+00:00

Add support for TPM ST33ZP24 spi.

The ST33ZP24 does have a spi interface.
The transport protocol is proprietary.

For spi we are relying only on DM_SPI.

tpm: Rename tpm_tis_infineon.h to tpm_tis.h and move infineon specific stuff in tpm_infineon.c

2016-01-29T04:01:22+00:00

I2C protocol is not standardize for TPM 1.2.
TIS prococol is define by the Trusted Computing Group and potentially
available on several TPMs.

tpm_tis_infineon.h header is not generic enough.

Rename tpm_tis_infineon.h to tpm_tis.h and move infineon specific
defines/variables to tpm_tis_infineon.c
