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

The current of-tree driver does not currently preserve the vTPM 1.2 and
vTPM 2.0 measurement log 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.

  tpm/kexec: Duplicate TPM measurement log in of-tree for kexec
  tpm: of: Call of_tpm_get_sml_parameters() to get base and size of log
