    commit 18b06652cd "tools: include u-boot version of sha256.h"
    unconditionally forced the sha256.h from u-boot to be used
    for tools instead of the host version. This is fragile though
    as it will also include the host version. Therefore move it
    to include/u-boot to join u-boot/md5.h etc which were renamed
    for the same reason.

  • be6c1529c   tpm: add AUTH1 cmds for LoadKey2 and GetPubKey ... Browse Code »

    Extend the tpm library with support for single authorized (AUTH1) commands
    as specified in the TCG Main Specification 1.2. (The internally used helper
    functions are implemented in a way that they could also be used for double
    authorized commands if someone needs it.)

    Provide enums with the return codes from the TCG Main specification.

    For now only a single OIAP session is supported.

    OIAP authorized version of the commands TPM_LoadKey2 and TPM_GetPubKey are
    provided. Both features are available using the 'tpm' command, too.

    Authorized commands are enabled with CONFIG_TPM_AUTH_SESSIONS. (Note that
    this also requires CONFIG_SHA1 to be enabled.)

  • 8732b0700   tpm: Add TPM command library ... Browse Code »

    TPM command library implements a subset of TPM commands defined in TCG
    Main Specification 1.2 that are useful for implementing secure boot.
    More TPM commands could be added out of necessity.

    You may exercise these commands through the 'tpm' command. However, the
    raw TPM commands are too primitive for writing secure boot in command
    interpreter scripts; so the 'tpm' command also provides helper functions
    to make scripting easier.

    For example, to define a counter in TPM non-volatile storage and
    initialize it to zero:

    $ tpm init
    $ tpm startup TPM_ST_CLEAR
    $ tpm nv_define d 0x1001 0x1
    $ tpm nv_write d 0x1001 0

    And then increment the counter by one:

    $ tpm nv_read d 0x1001 i
    $ setexpr.l i $i + 1
    $ tpm nv_write d 0x1001 $i
