+
+description: |
+  The TI K3 family of SoCs usually have one or more dual-core Arm Cortex R5F
+  processor subsystems/clusters (R5FSS). The dual core cluster can be used
+  either in a LockStep mode providing safety/fault tolerance features or in a
+  Split mode providing two individual compute cores for doubling the compute
+  capacity. These are used together with other processors present on the SoC
+  to achieve various system level goals.
+
+  Each Dual-Core R5F sub-system is represented as a single DTS node
+  representing the cluster, with a pair of child DT nodes representing
+  the individual R5F cores. Each node has a number of required or optional
+  properties that enable the OS running on the host processor to perform
+  the device management of the remote processor and to communicate with the
+  remote processor.

+      The R5F Sub-System device node should define two R5F child nodes, each
+      node representing a TI instantiation of the Arm Cortex R5F core. There
+      are some specific integration differences for the IP like the usage of
+      a Region Address Translator (RAT) for translating the larger SoC bus
+      addresses into a 32-bit address space for the processor.
+
+      Each R5F core has an associated 64 KB of Tightly-Coupled Memory (TCM)
+      internal memories split between two banks - TCMA and TCMB (further
+      interleaved into two banks TCMB0 and TCMB1). These memories (also called
+      ATCM and BTCM) provide read/write performance on par with the core's L1
+      caches. Each of the TCMs can be enabled or disabled independently and
+      either of them can be configured to appear at that R5F's address 0x0.
+
+      The cores do not use an MMU, but has a Region Address Translater
+      (RAT) module that is accessible only from the R5Fs for providing
+      translations between 32-bit CPU addresses into larger system bus
+      addresses. Cache and memory access settings are provided through a
+      Memory Protection Unit (MPU), programmable only from the R5Fs.
