+ * We map various devices into the container MR at their architected

+ * and includes the NVIC, the System Control Space (system registers),
+ * the systick timer, and for CPUs with the Security extension an NS
+ * banked version of all of these.
+ *
+ * The default behaviour for unimplemented registers/ranges
+ * (for instance the Data Watchpoint and Trace unit at 0xe0001000)
+ * is to RAZ/WI for privileged access and BusFault for non-privileged
+ * access.
+ *
+ * The NVIC and System Control Space (SCS) starts at 0xe000e000
+ * and looks like this:
+ * 0x004 - ICTR
+ * 0x010 - 0xff - systick
+ * 0x100..0x7ec - NVIC
+ * 0x7f0..0xcff - Reserved
+ * 0xd00..0xd3c - SCS registers
+ * 0xd40..0xeff - Reserved or Not implemented
+ * 0xf00 - STIR
+ *
+ * Some registers within this space are banked between security states.
+ * In v8M there is a second range 0xe002e000..0xe002efff which is the
+ * NonSecure alias SCS; secure accesses to this behave like NS accesses
+ * to the main SCS range, and non-secure accesses (including when
+ * the security extension is not implemented) are RAZ/WI.
+ * Note that both the main SCS range and the alias range are defined
+ * to be exempt from memory attribution (R_BLJT) and so the memory
+ * transaction attribute always matches the current CPU security
+ * state (attrs.secure == env->v7m.secure). In the v7m_sysreg_ns_ops
+ * wrappers we change attrs.secure to indicate the NS access; so
+ * generally code determining which banked register to use should
+ * use attrs.secure; code determining actual behaviour of the system
+ * should use env->v7m.secure.
+ *
+ * Within the PPB space, some MRs overlap, and the priority
+ * of overlapping regions is:
+ * - default region (for RAZ/WI and BusFault) : -1
+ * - system register regions (provided by the NVIC) : 0
+ * - systick : 1
+ * This is because the systick device is a small block of registers
+ * in the middle of the other system control registers.
