88 bool "Enable an early debug UART for debugging"
89 help
90 The debug UART is intended for use very early in U-Boot to debug
91 problems when an ICE or other debug mechanism is not available.
92
93 To use it you should:
94 - Make sure your UART supports this interface
95 - Enable CONFIG_DEBUG_UART
96 - Enable the CONFIG for your UART to tell it to provide this interface
97 (e.g. CONFIG_DEBUG_UART_NS16550)
98 - Define the required settings as needed (see below)
99 - Call debug_uart_init() before use
100 - Call debug_uart_putc() to output a character
101
102 Depending on your platform it may be possible to use this UART before
103 a stack is available.
104
105 If your UART does not support this interface you can probably add
106 support quite easily. Remember that you cannot use driver model and
107 it is preferred to use no stack.
108
109 You must not use this UART once driver model is working and the
110 serial drivers are up and running (done in serial_init()). Otherwise
111 the drivers may conflict and you will get strange output.
