[PATCH v3 0/3] Improve U-Boot's TPM handling in the non-EFI case

[Ludwig Nussel]

U-Boot might be the first component to start the event log, eg when
used in qemu. So allocate and attach the TPM event log to the TPM
device if not initialized yet. The address is copied into the device
tree for the kernel so the event log is accessible from Linux
userspace too.

Changes in v3:
- fix test failure
- sync description with cover letter

Changes in v2:
- fix return value handling
- imply DEVRES in config TPM
- use fdt_getprop for reading property
- don't wrap #include in #if
- fix memory leak in error case of tcg2_log_prepare_buffer
- handle NULL elog parameter in tcg2_measurement_term
- use CONFIG_TPM2_EVENT_LOG_SIZE
- pass log_size instead of position in dt

Ludwig Nussel (3):
  test: include mapmem.h explicitly
  tpm: print all PCRs from pcr_read
  tpm: allocate tpm event log if missing
