/* Handling of which devices should be available only to secure
* code is usually done differently for M profile than for A profile.
* Instead of putting some devices only into the secure address space,
* devices exist in both address spaces but with hard-wired security
* permissions that will cause the CPU to fault for non-secure accesses.
*
* The IoTKit has an IDAU (Implementation Defined Access Unit),
* which specifies hard-wired security permissions for different
* areas of the physical address space. For the IoTKit IDAU, the
* top 4 bits of the physical address are the IDAU region ID, and
* if bit 28 (ie the lowest bit of the ID) is 0 then this is an NS
* region, otherwise it is an S region.
*
* The various devices and RAMs are generally all mapped twice,
* once into a region that the IDAU defines as secure and once
* into a non-secure region. They sit behind either a Memory
* Protection Controller (for RAM) or a Peripheral Protection
* Controller (for devices), which allow a more fine grained
* configuration of whether non-secure accesses are permitted.
*
* (The other place that guest software can configure security
* permissions is in the architected SAU (Security Attribution
* Unit), which is entirely inside the CPU. The IDAU can upgrade
* the security attributes for a region to more restrictive than
* the SAU specifies, but cannot downgrade them.)

* configure it to either pass through or reject transactions.
* Rejected transactions may be configured to either be aborted, or to
* behave as RAZ/WI. An interrupt can be signalled for a rejected transaction.
*
* The PPC has no register interface -- it is configured purely by a
* collection of input signals from other hardware in the system. Typically
* they are either hardwired or exposed in an ad-hoc register interface by
* the SoC that uses the PPC.
*
* This QEMU model can be used to model either the AHB5 or APB4 TZ PPC,
* since the only difference between them is that the AHB version has a
* "default" port which has no security checks applied. In QEMU the default
* port can be emulated simply by wiring its downstream devices directly
* into the parent address space, since the PPC does not need to intercept
* transactions there.
*
* In the hardware, selection of which downstream port to use is done by
* the user's decode logic asserting one of the hsel[] signals. In QEMU,
* we provide 16 MMIO regions, one per port, and the user maps these into
* the desired addresses to implement the address decode.
*
* QEMU interface:
* + sysbus MMIO regions 0..15: MemoryRegions defining the upstream end
* of each of the 16 ports of the PPC
* + Property "port[0..15]": MemoryRegion defining the downstream device(s)
* for each of the 16 ports of the PPC
* + Named GPIO inputs "cfg_nonsec[0..15]": set to 1 if the port should be
* accessible to NonSecure transactions
* + Named GPIO inputs "cfg_ap[0..15]": set to 1 if the port should be
* accessible to non-privileged transactions
* + Named GPIO input "cfg_sec_resp": set to 1 if a rejected transaction should
* result in a transaction error, or 0 for the transaction to RAZ/WI
* + Named GPIO input "irq_enable": set to 1 to enable interrupts
* + Named GPIO input "irq_clear": set to 1 to clear a pending interrupt
* + Named GPIO output "irq": set for a transaction-failed interrupt
* + Property "NONSEC_MASK": if a bit is set in this mask then accesses to
* the associated port do not have the TZ security check performed. (This
* corresponds to the hardware allowing this to be set as a Verilog
* parameter.)
