/* 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 ARMSSE has an IDAU (Implementation Defined Access Unit),
|
|
* which specifies hard-wired security permissions for different
|
|
* areas of the physical address space. For the ARMSSE 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.)
