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

Turn this option on to enable an early console functionality in SPL

before the main console is being brought up. This can be useful in
|

situations where the main console is dependent on System Firmware
|
|
(SYSFW) being up and running, which is usually not the case during
|
|
the very early stages of boot. Using this early console functionality
|
|
will allow for an alternate serial port to be used to support things

like UART-based boot and early diagnostic messages until the main
|
|
console is ready to get activated.
