K3 SoCs are available in a number of device types such as
GP, HS-FS, EMU, etc. Like OMAP SoCs we can detect this at runtime
and should print this out as part of the SoC information line.
We add this as part of the common.c file as it will be used
to also modify our security state early in the device boot.

The first AM6x device was the AM654x, but being the first we named it
just AM6, since more devices have come out with this same prefix we
should switch it to the normal convention of using the full name of the
first compatibility device the series. This makes what device we are
talking about more clear and matches all the K3 devices added since.

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.

AM642 allows for booting from primary or backup boot media.
Both media can be chosen individually based on switch settings.
ROM looks for a valid image in primary boot media, if not found
then looks in backup boot media. In order to pass this boot media
information to boot loader, ROM stores a value at a particular
address. Add support for reading this information and determining
the boot media correctly.

Starting J7200 SoC, ROM supports for loading sysfw directly from boot
image. ROM passes this information on number of images that are loaded
to bootloader at certain location. Add support for storing this
information before it gets corrupted.

Add an api soc_is_j721e(), and use it to enable certain functionality
that is available only on j721e. This detection is needed when DT is not
available.

JTAG ID register is defined by IEEE 1149.1 for device identification.
Use this JTAG ID register for identifying AM65x[0] and J721E[1] devices
instead of using SoC specific registers.
