Subject: [PATCH v3 0/3] Locality support for tpm_crb

The tpm_crb driver should follow the policy of reserving and
relinquishing the locality it uses when multiple localities are used,
like when TXT is another locality.

[This is a resend of v3 as this has been asked from me for a few times
 now and there wasn't anything obvious to fix.]

Jarkko Sakkinen (3):
  tpm_crb: map locality registers
  tpm_crb: encapsulate crb_wait_for_reg_32
  tpm_crb: request and relinquish locality 0

v2: 
added sanity check for start address of the control area
v3:
do locality request/relinquish as part of send/recv
check priv->regs_h before using it
just assing the base address to regs_h instead of using crb_map_res
