2017.1 - 2016.3/4 Zynq UltraScale+ MPSoC: PMUFW will enable AIB (if existing) to isolate powered down components

Description

PMUFW enables AIBs only when RPU is powered down.

For other islands, the corresponding AIBs are not enabled, which might cause issues when a master tries to access the powered down blocks.

As a result, when an access is made to a powered down block, hangs or unexpected behavior might be observed.

Solution

Software running on a master in the system should ensure that no transactions are triggered for powered down blocks.

This issue is planned to be addressed in the 2017.2 release.
