+ * The debug UART is intended for use very early in U-Boot to debug problems
+ * when an ICE or other debug mechanism is not available.
+ *
+ * To use it you should:
+ * - Make sure your UART supports this interface
+ * - Enable CONFIG_DEBUG_UART
+ * - Enable the CONFIG for your UART to tell it to provide this interface
+ * (e.g. CONFIG_DEBUG_UART_NS16550)
+ * - Define the required settings as needed (see below)
+ * - Call debug_uart_init() before use
+ * - Call printch() to output a character
+ *
+ * Depending on your platform it may be possible to use this UART before a
+ * stack is available.
+ *
+ * If your UART does not support this interface you can probably add support
+ * quite easily. Remember that you cannot use driver model and it is preferred
+ * to use no stack.
+ *
+ * You must not use this UART once driver model is working and the serial
+ * drivers are up and running (done in serial_init()). Otherwise the drivers
+ * may conflict and you will get strange output.
+ *
+ *
+ * To enable the debug UART in your serial driver:
+ *
+ * - #include <debug_uart.h>
+ * - Define debug_uart_init(), trying to avoid using the stack
+ * - Define _debug_uart_putc() as static inline (avoiding stack usage)
+ * - Immediately afterwards, add DEBUG_UART_FUNCS to define the rest of the
+ * functionality (printch(), etc.)
+ */
