7 title: TI K3 R5F processor subsystems
10 - Suman Anna <s-anna@ti.com>
13 The TI K3 family of SoCs usually have one or more dual-core Arm Cortex R5F
14 processor subsystems/clusters (R5FSS). The dual core cluster can be used
20 AM64x SoCs do not support LockStep mode, but rather a new non-safety mode
21 called "Single-CPU" mode, where only Core0 is used, but with ability to use
25 firmware and can also be used as a remote processor with IPC communication.
27 Each Dual-Core R5F sub-system is represented as a single DTS node
30 properties that enable the OS running on the host processor to perform
31 the device management of the remote processor and to communicate with the
32 remote processor.

76 It should be either a value of 0 (Split mode) or 2 (Single-CPU mode) and
79 It should be set as 3 (Single-Core mode) which is also the default if
83 # R5F Processor Child Nodes:
87 "^r5f@[a-f0-9]+$":
90 The R5F Sub-System device node should define two R5F child nodes, each
94 addresses into a 32-bit address space for the processor. For AM62x,
95 the R5F Sub-System device node should only define one R5F child node
98 Each R5F core has an associated 64 KB of Tightly-Coupled Memory (TCM)
99 internal memories split between two banks - TCMA and TCMB (further
107 translations between 32-bit CPU addresses into larger system bus
