lib: tpm: Add command to list resources

2017-03-26T19:22:58Z

It is sometimes convenient to know how many and/or which resources are currently loaded into a TPG, e.g. to test is a flush operation succeeded. Hence, we add a command that lists the resources of a given type currently loaded into the TPM. Signed-off-by: Mario Six Reviewed-by: Simon Glass

tpm: Add function to load keys via their parent's SHA1 hash

2017-03-26T19:22:58Z

If we want to load a key into a TPM, we need to know the designated parent key's handle, so that the TPM is able to insert the key at the correct place in the key hierarchy. However, if we want to load a key whose designated parent key we also previously loaded ourselves, we first need to memorize this parent key's handle (since the handles for the key are chosen at random when they are inserted into the TPM). If we are, however, unable to do so, for example if the parent key is loaded into the TPM during production, and its child key during the actual boot, we must find a different mechanism to identify the parent key. To solve this problem, we add a function that allows U-Boot to load a key into the TPM using their designated parent key's SHA1 hash, and the corresponding auth data.

tpm: atmel_twi: Make compatible with DM I2C busses

2016-08-15T20:12:00Z

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.

tpm: st33zp24: Add tpm st33zp24 spi support

2016-01-29T04:01:22Z

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. Reviewed-by: Simon Glass Signed-off-by: Christophe Ricard
