As per the latest revision F of public TRM for DRA7/AM57xx SoCs SPRUHZ6F[1] (April 2016), with the exception of MPU power domain, all other power domains do not have memories capable of retention since they all operate in either "ON" or "OFF" mode. For these power states, the retention state for memories are basically ignored by PRCM and does not require to be programmed.
