title: AMD MicroBlaze/V BRAM-based Remote Processor
maintainers:
- Ben Levinsky <ben.levinsky@amd.com>
description: |
Soft-core processor subsystem instantiated in AMD programmable logic and
using dual-port BRAM for firmware storage and execution.
Hardware Architecture:
Host (PS) Programmable Logic (PL)
========= ======================

Soft-core CPU (MicroBlaze/V)
GPIO --------------------------> Proc Sys Reset ----> CPU Reset Signal
Clock -------------------------> Clock Distribution -> CPU Clock
Memory Architecture:
The dual-port BRAM allows simultaneous access from both processors:
- Port A: Connected to the host AXI BRAM controller for firmware loading
- Port B: Connected to the soft-core local memory bus for execution
The reg property describes the executable BRAM window in the processor-local
address space. The parent bus node translates that window to the system
physical address space by using standard devicetree address translation
through ranges. A clock input and a reset GPIO control the subsystem.

description:
The SoC Control Processor (SoCCP) is a small RISC-V MCU that controls USB
Type-C, battery charging and various other functions on Qualcomm SoCs, somewhat
analogous to traditional PC Embedded Controllers. This document describes
the Peripheral Authentication Service that loads and boots firmware for SoCCP.

description:
The TI AM33xx and AM43xx family of devices use a small Cortex M3 co-processor
(commonly referred to as Wakeup M3 or CM3) to help with various low power
tasks that cannot be controlled from the MPU. This CM3 processor requires a
firmware binary to accomplish this. A wkup_m3 device node is used to
represent the Wakeup M3 processor instance within the SoC. It is added as a
child node of the parent interconnect bus (l4_wkup) through which it is
accessible to the MPU.
