176 bool "Enable an early debug UART for debugging"
177 help
178 The debug UART is intended for use very early in U-Boot to debug
179 problems when an ICE or other debug mechanism is not available.
180
181 To use it you should:
182 - Make sure your UART supports this interface
183 - Enable CONFIG_DEBUG_UART
184 - Enable the CONFIG for your UART to tell it to provide this interface
185 (e.g. CONFIG_DEBUG_UART_NS16550)
186 - Define the required settings as needed (see below)
187 - Call debug_uart_init() before use
188 - Call debug_uart_putc() to output a character
189
190 Depending on your platform it may be possible to use this UART before
191 a stack is available.
192
193 If your UART does not support this interface you can probably add
194 support quite easily. Remember that you cannot use driver model and
195 it is preferred to use no stack.
196
197 You must not use this UART once driver model is working and the
198 serial drivers are up and running (done in serial_init()). Otherwise
199 the drivers may conflict and you will get strange output.

663 clock frequency is not defined in the device tree, the macro

672 Enable this option to allow device-tree control of the driver.
673
674 Normally this driver is controlled by the following options:
675
676 CONFIG_SYS_NS16550_PORT_MAPPED - indicates that port I/O is used for
677 access. If not enabled, then the UART is memory-mapped.
678 CONFIG_SYS_NS16550_MEM32 - if memory-mapped, indicates that 32-bit
679 access should be used (instead of 8-bit)
680 CONFIG_SYS_NS16550_REG_SIZE - indicates register width and also
681 endianness. If positive, big-endian access is used. If negative,
682 little-endian is used.
683
684 It is not a good practice for a driver to be statically configured,
685 since it prevents the same driver being used for different types of
686 UARTs in a system. This option avoids this problem at the cost of a
687 slightly increased code size.
