#  @brief Returns whether system has multiple possible TPMs or not
#
#  @par Detailed Description:
#      Returns whether system has multiple possible TPMs or not.
#      The MRW parser activates more complicated I2C master detection logic when
#      a system blueprint defines more than one TPM, in order to avoid having to
#      fix other non-compliant workbooks.  If every workbook is determined to
#      model the TPM and its I2C connection properly, this special case can be
#      removed.
#
#  @param[in] $targetsRef Reference to array of targets in the system
#  @retval 0 System does not have multiple possible TPMs
#  @retval 1 System has multiple possible TPMs
#
#  @TODO RTC: 189374 Remove API when all platforms' MRW supports dynamically
#      determining the processor driving it.
