ca0973741d arm: mach-k3: Move J721e SoC detection out of common section
This belongs in the J721e specific file as it is the only place
this is used. Any board level users should use the SOC driver.

While here, move the J721e and J7200 SoC IDs out of sys_proto.h
and into hardware.h. Use a macro borrowed from Rockchip and add
the rest of the SoC IDs for completeness and later use.

30e96a2401 arm: mach-k3: Move MSMC fixup to SoC level
The MSMC fixup is something we do based on SoC, not based on the board.
So this fixup does not belong in the board files. Move this to the
mach-k3 common file so that it does not have to be done in each board
that uses these SoCs.

We use ft_system_setup() here instead of ft_board_setup() since it is no
longer board level. Enable OF_SYSTEM_SETUP in the configurations that use
this to keep functionality the same.

fca27ee8b9 arch: mach-k3: Update board specific API name to K3 generic API name
Although the board_init_f API initialises the SoC, the API name is
incorrectly specified and misleads the functionality. This file should
only include k3-specific functionality. Change the API's name to something
more K3-specific and separate the function to make it more modular.

30de1ba0d3 arm: mach-k3: j7200: Add support for SOC detection
The J7200 SoC is a part of the K3 Multicore SoC architecture platform.
It is targeted for automotive gateway, vehicle compute systems,
Vehicle-to-Vehicle (V2V) and Vehicle-to-Everything (V2X) applications.
The SoC aims to meet the complex processing needs of modern embedded
products.

Some highlights of this SoC are:
* Dual Cortex-A72s in a single cluster, two clusters of lockstep
  capable dual Cortex-R5F MCUs and a Centralized Device Management and
  Security Controller (DMSC).
* Configurable L3 Cache and IO-coherent architecture with high data
  throughput capable distributed DMA architecture under NAVSS.
* Integrated Ethernet switch supporting up to a total of 4 external ports
  in addition to legacy Ethernet switch of up to 2 ports.
* Upto 1 PCIe-GEN3 controller, 1 USB3.0 Dual-role device subsystems,
  20 MCANs, 3 McASP, eMMC and SD, OSPI/HyperBus memory controller, I3C and
  I2C, eCAP/eQEP, eHRPWM among other peripherals.
* One hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
  management.

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.

f9380a730d armv7R: K3: am654: Shut down R5 core after ATF startup on A53
Rather than simply parking the R5 core in WFE after starting up ATF
on A53 instead use SYSFW API to properly shut down the R5 CPU cores
as well as associated timer resources that were pre-allocated. This
allows software further downstream to properly and gracefully bring
the R5 cores back online if desired.

03facc7271 board: ti: am654: Use EEPROM-based board detection
The TI AM654x EVM base board and the associated daughtercards have on-
board I2C-based EEPROMs containing board configuration data. Use the
board detection infrastructure introduced earlier to do the following:

1) Parse the AM654x EVM base board EEPROM and populate items like board
   name and MAC addresses into the TI common EEPROM data structure
   residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing the associated
   presence signals via an I2C-based GPIO expander. Then, if such a
   card is found, parse the data such as additional Ethernet MAC
   addresses from its on-board EEPROM and populate into U-Boot
   accordingly
3) Dynamically create an U-Boot ENV variable called overlay_files
   containing a list of daugherboard-specific DTB overlays based on
   daughercards found.

This patch adds support for the AM654x base board ("AM6-COMPROCEVM")
as well as for the IDK ("AM6-IDKAPPEVM"), OLDI LCD ("OLDI-LCD1EVM")
PCIe/USB3.0 ("SER-PCIEUSBEVM"), 2 Lane PCIe/USB2.0 ("SER-PCIE2LEVM"),
and general purpuse ("AM6-GPAPPEVM") daughtercards.

a9a84480f4 arm: k3: Add support for updating msmc dt node
Certain parts of msmc sram can be used by DMSC or can be
marked as L3 cache. Since the available size can vary, changing
DT every time the size varies might be painful. So, query this
information using TISCI cmd and fixup the DT for kernel.
Fixing up DT does the following:
- Create a sram node if not available
- update the reg property with available size
- update ranges property
- loop through available sub nodes and delete it if:
	- mentioned size is out if available range
	- subnode represents l3 cache or dmsc usage.

06bda1259f ram: Introduce K3 AM654 DDR Sub System driver
K3 based AM654 devices has DDR memory subsystem that comprises
Synopys DDR controller, Synopsis DDR phy and wrapper logic to
intergrate these blocks into the device. This DDR subsystem
provides an interface to external SDRAM devices. Adding support
for the initialization of the external SDRAM devices by
configuring the DDRSS registers and using the buitin PHY
routines.
