[PATCH 0/2] use TPM device with CRB over FF-A when kernel boot with pkvm

[Yeoreum Yun]

To use TPM device iwth CRB over FF-A, it would be good to be compiled:
  - CONFIG_ARM_FFA_TRANSPORT as bulit-in
  - CONFIG_TCG_ARM_CRB_FFA as built-in

to integrate with IMA subsystem otherwise, it couldn't generate the
boot_aggreate log with the PCR value.

Unfortuately, kernel fails to probe the TPM device
when it boots with kvm-arm.mode=protected since the FF-A calls
(FFA_SEND_DIRECT_MSG/MSG2) are failed when CONFIG_ARM_FFA_TRANSPORT=y.

This patch series resolves failure of the TPM device when
kernel boots with kvm-arm.mode=protected and based on v6.18-rc3.

Yeoreum Yun (2):
  KVM: arm64: fix FF-A call failure when ff-a driver is built-in
  KVM: arm64: support optional calls of FF-A v1.2
