3bc1572068 arm64: dts: ti: k3-am65: Change #address-cells and #size-cells of interconnect to 2
AM65 has two PCIe controllers and each PCIe controller has '2' address
spaces one within the 4GB address space of the SoC and the other above
the 4GB address space of the SoC (cbass_main) in addition to the
register space. The size of the address space above the 4GB SoC address
space is 4GB. These address ranges will be used by CPU/DMA to access
the PCIe address space. In order to represent the address space above
the 4GB SoC address space and to represent the size of this address
space as 4GB, change address-cells and size-cells of interconnect to 2.

Since OSPI has similar need in MCU Domain Memory Map, change
address-cells and size-cells of cbass_mcu interconnect also to 2.

d0a064bec7 arm64: dts: ti: Add support for AM654 EVM base board
The EValuation Module(EVM) platform for AM654 consists of a
common Base board + one or more of daughter cards, which include:
a) "Personality Modules", which can be specific to a profile, such as
 ICSSG enabled or Multi-media (including audio).
b) SERDES modules, which may be 2 lane PCIe or two port PCIe + USB2
c) Camera daughter card
d) various display panels

Among other options. There are two basic configurations defined which
include an "EVM" configuration and "IDK" (Industrial development kit)
which differ in the specific combination of daughter cards that are
used.

To simplify support, we choose to support just the base board as the
core device tree file and all daughter cards would be expected to be
device tree overlays.

ea47eed33a arm64: dts: ti: Add Support for AM654 SoC
The AM654 SoC is a lead device of the K3 Multicore SoC architecture
platform, targeted for broad market and industrial control with aim to
meet the complex processing needs of modern embedded products.

Some highlights of this SoC are:
* Quad ARMv8 A53 cores split over two clusters
* GICv3 compliant GIC500
* Configurable L3 Cache and IO-coherent architecture
* Dual lock-step capable R5F uC for safety-critical applications
* High data throughput capable distributed DMA architecture under NAVSS
* Three Gigabit Industrial Communication Subsystems (ICSSG), each with dual
  PRUs and dual RTUs
* Hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
* Centralized System Controller for Security, Power, and Resource
  management.
* Dual ADCSS, eQEP/eCAP, eHRPWM, dual CAN-FD
* Flash subsystem with OSPI and Hyperbus interfaces
* Multimedia capability with CAL, DSS7-UL, SGX544, McASP
* Peripheral connectivity including USB3, PCIE, MMC/SD, GPMC, I2C, SPI,
  GPIO

See AM65x Technical Reference Manual (SPRUID7, April 2018)
for further details: http://www.ti.com/lit/pdf/spruid7

NOTE:
1. AM654 is the first of the device variants, hence we introduce a
   generic am65.dtsi.
2. We indicate the proper bus topology, the ranges are elaborated in
   each bus segment instead of using the top level ranges to make sure
   that peripherals in each segment use the address space accurately.
3. Peripherals in each bus segment is maintained in a separate dtsi
   allowing for reuse in different bus segment representation from a
   different core such as R5. This is also the reason for maintaining a
   1-1 address map in the ranges.
4. Cache descriptions follow the ARM64 standard description.

Further tweaks may be necessary as we introduce more complex devices,
but can be introduced in context of the device introduction.
