+title: Secure AHB to IP Slave bus (AIPSTZ) bridge

+description:
+ The secure AIPS bridge (AIPSTZ) acts as a bridge for AHB masters issuing
+ transactions to IP Slave peripherals. Additionally, this module offers a=
ccess
+ control configurations meant to restrict which peripherals a master can
+ access.
