+         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.
