  • abdc7b8a2   tpm: Convert to use a device parameter ... Browse Code »

    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.

  • 51f00c170   tpm: Export the open/close functions ... Browse Code »

    At present these functions are not accessible outside the TPM library, but
    in some cases we need to call them. Export them in the header file and add
    a define for the SHA1 digest size.

    Also adjust tpm_open() to call tpm_close() first so that the TPM is in a
    known state before opening (e.g. by a previous phase of U-Boot).

  • f6872816c   tpm: add macros to enhance TPM commands readability ... Browse Code »

    TPM commands are much easier to read/write with these macros that will
    transform words or integers into byte strings. This way, there is no
    need to call pack_byte_string() while all variable length in a command
    are known (and at must 4 bytes, which is a lot of them).

  • d677bfe2f   tpm: disociate TPMv1.x specific and generic code ... Browse Code »

    There are no changes in this commit but a new organization of the code
    as follow.

    * cmd/ directory:
    > move existing code from cmd/tpm.c in cmd/tpm-common.c
    > move specific code in cmd/tpm-v1.c
    > create a specific header file with generic definitions for
    commands only called cmd/tpm-user-utils.h

    * lib/ directory:
    > move existing code from lib/tpm.c in lib/tpm-common.c
    > move specific code in lib/tpm-v1.c
    > create a specific header file with generic definitions for
    the library itself called lib/tpm-utils.h

    * include/ directory:
    > move existing code from include/tpm.h in include/tpm-common.h
    > move specific code in include/tpm-v1.h

    Code designated as 'common' is compiled if TPM are used. Code designated
    as 'specific' is compiled only if the right specification has been
    selected.

    All files include tpm-common.h.
    Files in cmd/ include tpm-user-utils.h.
    Files in lib/ include tpm-utils.h.
    Depending on the specification, files may include either (not both)
    tpm-v1.h or tpm-v2.h.
