tpm: Allow disabling platform hierarchy with TPM2

2021-03-02T20:53:37+00:00

With TPM2 we don't actually lock the TPM once verified boot is finished. Instead we disable the platform hierarchy which serves the same purpose. Add an implementation of this so we can safely boot into the kernel. Signed-off-by: Simon Glass Acked-by: Ilias Apalodimas

tpm: Add TPM2 support for write_lock

2021-03-02T20:53:37+00:00

Implement this API function for TPM2. Signed-off-by: Simon Glass Acked-by: Ilias Apalodimas

tpm: Add TPM2 support for read/write values

2021-03-02T20:53:37+00:00

tpm: Add an implementation of define_space

2021-03-02T20:53:37+00:00

Add support for this so that the TPM can be set up for use with Chromium OS verified boot. Signed-off-by: Simon Glass Acked-by: Ilias Apalodimas

tpm: Reduce duplication in a few functions

2021-03-02T20:53:37+00:00

Update tpm2_clear() and tpm2_pcr_extend() so that the command size is not repeated twice. Add a small comment to the latter. Signed-off-by: Simon Glass Reviewed-by: Ilias Apalodimas

tpm: use more than sha256 on pcr_extend

2020-12-03T20:22:40+00:00

The current tpm2_pcr_extend is hardcoded using SHA256. Let's make the actual command to the TPM2 configurable so we can support a wider range of algorithms and keep the current command line as-is i.e limited to SHA256 only Signed-off-by: Ilias Apalodimas Reviewed-by: Simon Glass

tpm: Change response length of tpm2_get_capability()

2020-11-09T16:28:18+00:00

For implementing the EFI_TCG2_PROTOCOL we need the count field returned by the TPM when reading capabilities via tpm2_get_capability(). Adjust the implementation of the 'tpm2 get_capability' command accordingly. Suggested-by: Heinrich Schuchardt Signed-off-by: Ilias Apalodimas Reviewed-by: Heinrich Schuchardt

tpm: add TPM2_GetRandom command support

common: Drop linux/bitops.h from common header

2020-05-19T01:19:23+00:00

Move this uncommon header out of the common header. Signed-off-by: Simon Glass

tpm: Convert to use a device parameter

2018-11-29T16:30:06+00:00

At present many TPM calls assume there is only one TPM in the system and look up this TPM themselves. This is inconsistent with driver model, which expects all driver methods to have a device parameter. Update the code to correct this. Signed-off-by: Simon Glass
