[PATCH v2 0/3] tpm: Preserve TPM measurement log across kexec

[Stefan Berger]

The of-tree driver does not currently preserve the IBM vTPM 1.2 and
vTPM 2.0 measurement logs across a kexec. This series fixes this for the
kexec_file_load() syscall using the flattened device tree (fdt) to
carry the measurement log's buffer across kexec.

v2:
 - rearranged patches
 - fixed compilation issues for x86

Stefan Berger (3):
  tpm: of: Move of-tree specific code from tpm driver into of driver
  of: kexec: Refactor IMA buffer related functions to make them reusable
  tpm/kexec: Duplicate TPM measurement log in of-tree for kexec
