776e25788c arm: dts: k3-am64-main: Reserve OCMRAM for DMSC-lite and secure proxy communication
The final 128KB in SRAM is reserved by default for DMSC-lite code and
secure proxy communication buffer. The memory region used for DMSC-lite
code can be optionally freed up by secure firmware API[1]. However, the
buffer for secure proxy communication is not configurable. This default
hardware configuration is unique for AM64.

Therefore, indicate the area reserved for DMSC-lite code and secure proxy
communication buffer in the oc_sram device tree node.

5242c6a432 configs: am64x_evm_a53_defconfig: Move TF-A load address to 0x701c0000
Earlier, the region 0x701c0000 to 0x701dffff was firewalled off because of
a bug in SYSFW. In the v2021.05 release of SYSFW this bug has been fixed
and this region can now be used for other allocations.

Therefore, move TF-A's load address to 0x701c0000 and update its location
in the device tree node. Also, increase the size allocated for TF-A to
account for future expansions.

defd62ca13 arm: dts: k3-am64-main: Update the location of ATF in SRAM and increase its max size
Due to a limitation for USB DFU boot mode, SPL load address has to be less
than  or equal to 0x70001000. So, load address of SPL and ATF have been
moved to 0x70000000 and 0x701a0000 respectively.

Also, the maximum size of ATF has been increased to 0x1c000 [1].

Therefore, update ATF's location and maximum size accordingly in the device
tree file.

58211db0a8 arm: dts: ti: Add Support for AM642 SoC
The AM642 SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration to enable applications such as
Motor Drives, PLC, Remote IO and IoT Gateways.

Some highlights of this SoC are:
* Dual Cortex-A53s in a single cluster, two clusters of dual Cortex-R5F
  MCUs, and a single Cortex-M4F.
* Two Gigabit Industrial Communication Subsystems (ICSSG).
* Integrated Ethernet switch supporting up to a total of two external
  ports.
* PCIe-GEN2x1L, USB3/USB2, 2xCAN-FD, eMMC and SD, UFS, OSPI memory
  controller, QSPI, I2C, eCAP/eQEP, ePWM, ADC, among other
  peripherals.
* Centralized System Controller for Security, Power, and Resource
  Management (DMSC).

See AM64X Technical Reference Manual (SPRUIM2, Nov 2020)
for further details: https://www.ti.com/lit/pdf/spruim2

Introduce basic support for the AM642 SoC to enable SD/MMC boot.
Introduce a limited set of MAIN domain peripherals under cbass_main and
a set of MCU domain peripherals under cbass_mcu.
