+ bool "Set loadable kernel module data as NX and text as RO"
+ depends on MODULES
+ ---help---
+ This option helps catch unintended modifications to loadable
+ kernel module's text and read-only data. It also prevents execution
+ of module data. Such protection may interfere with run-time code
+ patching and dynamic kernel tracing - and they might also protect
+ against certain classes of kernel exploits.

+menuconfig CORESIGHT
+ bool "CoreSight Tracing Support"
+ select ARM_AMBA
+ help
+ This framework provides a kernel interface for the CoreSight debug
+ and trace drivers to register themselves with. It's intended to build
+ a topological view of the CoreSight components based on a DT
+ specification and configure the right serie of components when a
+ trace source gets enabled.

+config CORESIGHT_LINKS_AND_SINKS
+ bool "CoreSight Link and Sink drivers"
+ help
+ This enables support for CoreSight link and sink drivers that are
+ responsible for transporting and collecting the trace data

+ entity at run time to form a complete trace path.
+
+config CORESIGHT_LINK_AND_SINK_TMC
+ bool "Coresight generic TMC driver"
+ depends on CORESIGHT_LINKS_AND_SINKS
+ help
+ This enables support for the Trace Memory Controller driver. Depending

+ added features.
+
+config CORESIGHT_SINK_TPIU
+ bool "Coresight generic TPIU driver"
+ depends on CORESIGHT_LINKS_AND_SINKS
+ help
+ This enables support for the Trace Port Interface Unit driver, responsible
+ for bridging the gap between the on-chip coresight components and a trace

+ case capturing more traces than the on-board coresight memory can handle.
