tpm: Tidy up use of size_t

2016-10-11T03:55:33+00:00

We should consistently use %z with size_t, and avoid passing a uint32_t as
a size_t value. Fix these issues to avoid warnings on 64-bit machines.

tpm: atmel_twi: Make compatible with DM I2C busses

2016-08-15T20:12:00+00:00

Commit 302c5db ("dm: tpm: Add Driver Model support for tpm_atmel_twi
driver") converted the Atmel TWI TPM driver itself to driver model, but
kept the legacy-style i2c_write/i2c_read calls.

Commit 3e7d940 ("dm: tpm: Every TPM drivers should depends on DM_TPM")
then made DM_I2C a dependency of the driver, effectively forcing users
to turn on CONFIG_DM_I2C_COMPAT to get it to work.

This patch adds the necessary dm_i2c_write/dm_i2c_read calls to make the
driver compatible with DM, but also keeps the legacy calls in ifdefs, so
that the driver is now compatible with both DM and non-DM setups.

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
