• 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.

  This driver was originally written against Chromium OS circa 2012. A few
  new features have been added. Enhance the TPM driver to match. This mostly
  includes a few new messages and properly modelling whether a particular
  'space' is present or not.

  Use an enum for command values instead of open-coding them. This removes
  the need for comments. Also make sure the driver returns proper error
  numbers instead of -1.

• 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.
