147 bool "Enable an early debug UART for debugging"
148 help
149 The debug UART is intended for use very early in U-Boot to debug
150 problems when an ICE or other debug mechanism is not available.
151
152 To use it you should:
153 - Make sure your UART supports this interface
154 - Enable CONFIG_DEBUG_UART
155 - Enable the CONFIG for your UART to tell it to provide this interface
156 (e.g. CONFIG_DEBUG_UART_NS16550)
157 - Define the required settings as needed (see below)
158 - Call debug_uart_init() before use
159 - Call debug_uart_putc() to output a character
160
161 Depending on your platform it may be possible to use this UART before
162 a stack is available.
163
164 If your UART does not support this interface you can probably add
165 support quite easily. Remember that you cannot use driver model and
166 it is preferred to use no stack.
167
168 You must not use this UART once driver model is working and the
169 serial drivers are up and running (done in serial_init()). Otherwise
170 the drivers may conflict and you will get strange output.
