159 The debug UART is intended for use very early in U-Boot to debug
163 - Make sure your UART supports this interface
164 - Enable CONFIG_DEBUG_UART
165 - Enable the CONFIG for your UART to tell it to provide this interface
167 - Define the required settings as needed (see below)
168 - Call debug_uart_init() before use
169 - Call debug_uart_putc() to output a character
