  When in pack_byte_string() memcpy() is called for size 0 the source buffer
  address has no relevance. So we can use NULL here.

• 0a60a0a65   tpm: Remove use of build-time TPM versions ... Browse Code »

  There is only one place in the code which assumes at build-time that we
  are using either a v1 or a v2 TPM. Fix this up and add a new function to
  return the version of a TPM.

  Supported TPM versions (v1 and v2) can be enabled independently and it is
  possible to use both versions at once. This is useful for sandbox when
  running tests.

• 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.

• 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.
