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. Signed-off-by: Dave Gerlach <d-gerlach@ti.com>
