Stuart, I did not go through this but this does not look correct even with
a quick peak:

config TCG_ARM_CRB_FFA                                                                                                                                                         
       ~~~~~~~~~~~~~~~
       TCG_FTPM_FFA (and Kconfig put before TCG_FTPM_TEE)


        tristate "TPM CRB over Arm FF-A Transport"                                                                                                                             
        depends on ARM_FFA_TRANSPORT                                                                                                                                           
        default y if (TCG_CRB && ARM_FFA_TRANSPORT)                                                                                                                            
                                 ~~~~~~~~~~~~~~~~~
				 redundant given "depends on"

        help                                                                                                                                                                   
          If the Arm FF-A transport is used to access the TPM say Yes.                                                                                                         
          To compile this driver as a module, choose M here; the module                                                                                                        
          will be called tpm_crb_ffa.                                                                                                                                          

So I'll drop the whole series from my tree for the moment and you'll
have to respin.
              
BR, Jarkko
