6248b20e32 arm64: dts: ti: k3-am64: Add MIT license along with GPL-2.0
Modify license to include dual licensing as GPL-2.0-only OR MIT
license for SoC and TI evm device tree files. This allows for Linux
kernel device tree to be used in other Operating System ecosystems
such as Zephyr or FreeBSD.

While at this, update the GPL-2.0 to be GPL-2.0-only to be in sync
with latest SPDX conventions (GPL-2.0 is deprecated).

While at this, update the TI copyright year to sync with current year
to indicate license change (and add it at least for one file which was
missing TI copyright).

880932e657 arm64: dts: Update cache properties for ti
The DeviceTree Specification v0.3 specifies that the cache node
'compatible' and 'cache-level' properties are 'required'. Cf.
s3.8 Multi-level and Shared Cache Nodes
The 'cache-unified' property should be present if one of the
properties for unified cache is present ('cache-size', ...).

Update the Device Trees accordingly.

a27a93bf70 arm64: dts: ti: k3-am642: Fix the L2 cache sets
A53's L2 cache[1] on AM642[2] is 256KB. A53's L2 is fixed line length
of 64 bytes and 16-way set-associative cache structure.

256KB of L2 / 64 (line length) = 4096 ways
4096 ways / 16 = 256 sets

Fix the l2 cache-sets.

8abae9389b arm64: 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 ramdisk or MMC
boot. Introduce the sdhci, i2c, spi, and uart MAIN domain periperhals
under cbass_main and the i2c, spi, and uart MCU domain periperhals
under cbass_mcu.
