AM6421: Can only Cortex-R5F be used without Cortex-A53 booting ?

Hi,

My customer wants to use only two Cortex-R5Fs on AM6421 for reducing power consumption in some product line-up. Is it possible to not boot A53 core ? For example, is the following start-up possible ?

PORZ
         -> DMSC starts
                       -> R5F0 starts
                                    -> R5F1 starts

A53 is not booted by R5F
