157 bool "Enable an early debug UART for debugging"
158 help
159 The debug UART is intended for use very early in U-Boot to debug
160 problems when an ICE or other debug mechanism is not available.
161
162 To use it you should:
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
166 (e.g. CONFIG_DEBUG_UART_NS16550)
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
170
171 Depending on your platform it may be possible to use this UART before
172 a stack is available.
173
174 If your UART does not support this interface you can probably add
175 support quite easily. Remember that you cannot use driver model and
176 it is preferred to use no stack.
177
178 You must not use this UART once driver model is working and the
179 serial drivers are up and running (done in serial_init()). Otherwise
180 the drivers may conflict and you will get strange output.
