de3db25231 arm: mach-k3: am62: Add CTRLMMR_WKUP_JTAG_DEVICE_ID register definition
Add register address and relevant bitmasks and shifts.
Allow reading these information:
- device identification
- number of cores (part of device identification)
- features (currently: PRU / no PRU)
- security
- functional safety
- speed grade
- temperature grade
- package

2aee173ba0 arm: mach-k3: Make release_resources_for_core_shutdown() common
This function is the same for each device when it needs to shutdown
the R5 core. Move this to the common section and move the remaining
device specific ID list to the device hardware include.

d3882531c3 arm: mach-k3: am62: move scratch board area to HSM RAM
On high security devices, ROM enables firewalls to protect the OCSRAM
region access during bootup. Only after TIFS has started (and had
time to disable the OCSRAM firewall region) will we have write access to
the region.

So, move scratch board area to HSM RAM.

e1e8fdfa6d arm: mach-k3: Move hardware handling to common files
These hardware register definitions are common for all K3, remove
duplicate data them by moving them to hardware.h.

While here do some minor whitespace cleanup + grouping.

169582025a arm64: mach-k3: am625_init: Probe ESM nodes
On AM62x devices, main ESM error event outputs can be routed to
MCU ESM as inputs. So, two ESM device nodes are expected in the
device tree : one for main ESM and another one for MCU ESM.
MCU ESM error output can trigger the reset logic to reset
the device when CTRLMMR_MCU_RST_CTRL:MCU_ESM_ERROR_RESET_EN_Z is
set to '0'.

d98e860051 arm: mach-k3: Introduce the basic files to support AM62
The AM62 SoC family is the follow on AM335x built on K3 Multicore SoC
architecture platform, providing ultra-low-power modes, dual display,
multi-sensor edge compute, security and other BOM-saving integration.
The AM62 SoC targets broad market to enable applications such as
Industrial HMI, PLC/CNC/Robot control, Medical Equipment, Building
Automation, Appliances and more.

Some highlights of this SoC are:

* Quad-Cortex-A53s (running up to 1.4GHz) in a single cluster.
  Pin-to-pin compatible options for single and quad core are available.
* Cortex-M4F for general-purpose or safety usage.
* Dual display support, providing 24-bit RBG parallel interface and
  OLDI/LVDS-4 Lane x2, up to 200MHz pixel clock support for 2K display
  resolution.
* Selectable GPUsupport, up to 8GFLOPS, providing better user experience
  in 3D graphic display case and Android.
* PRU(Programmable Realtime Unit) support for customized programmable
  interfaces/IOs.
* Integrated Giga-bit Ethernet switch supporting up to a total of two
  external ports (TSN capable).
* 9xUARTs, 5xSPI, 6xI2C, 2xUSB2, 3xCAN-FD, 3x eMMC and SD, GPMC for
  NAND/FPGA connection, OSPI memory controller, 3xMcASP for audio,
  1x CSI-RX-4L for Camera, eCAP/eQEP, ePWM, among other peripherals.
* Dedicated Centralized System Controller for Security, Power, and
  Resource Management.
* Multiple low power modes support, ex: Deep sleep,Standby, MCU-only,
  enabling battery powered system design.

AM625 is the first device of the family. Add DT bindings for the same.
