Subject: [PATCH v2 0/8] tpm: factor out tpm1 code into tpm1-cmd.c

Move TPM1 implementation from tpm-interface.c to tpm1-cmd.c
similarly to tpm2-cmd.c, as well as move TPM2 open code flows
into new functions to tpm2-cmd.c
The functions in tpm-interface.c should now be in form:


int tpm_func(struct tpm_chip *chip)
{
 if (chip->flags & TPM_CHIP_FLAG_TPM2)
                return tpm2_func(chip);
        else
                return tpm1_func(chip);
}

This is work in progress of possible dropping compiling out one tpm 1.x or tpm 2.x in case
not needed on a target platform.

V2: 1. This resend includes more patches that cleans the tpm-interface.c
completely 
    2. Fix notorious typo tmp -> tpm, in some patches

Tomas Winkler (8):
  tpm: move tpm1_pcr_extend to tpm1-cmd.c
  tpm: move tpm_getcap to tpm1-cmd.c
  tpm: factor out tpm1_get_random into tpm1-cmd.c
  tpm: move tpm1 selftest code from tpm-interface tpm1-cmd.c
  tpm: factor out tpm1 pm suspend flow into tpm1-cmd.c
  tpm: factor out tpm_startup function
  tpm: Move pcr extend to tpm2-cmd.c
  tpm: move tpm2 code validation to tpm2-space.c
