160 bool "Enable an early debug UART for debugging"
161 help
162 The debug UART is intended for use very early in U-Boot to debug
163 problems when an ICE or other debug mechanism is not available.
164
165 To use it you should:
166 - Make sure your UART supports this interface
167 - Enable CONFIG_DEBUG_UART
168 - Enable the CONFIG for your UART to tell it to provide this interface
169 (e.g. CONFIG_DEBUG_UART_NS16550)
170 - Define the required settings as needed (see below)
171 - Call debug_uart_init() before use
172 - Call debug_uart_putc() to output a character
173
174 Depending on your platform it may be possible to use this UART before
175 a stack is available.
176
177 If your UART does not support this interface you can probably add
178 support quite easily. Remember that you cannot use driver model and
179 it is preferred to use no stack.
180
181 You must not use this UART once driver model is working and the
182 serial drivers are up and running (done in serial_init()). Otherwise
183 the drivers may conflict and you will get strange output.

635 Support NS16550 UART or compatible. This can be enabled in the
636 device tree with the correct input clock frequency. If the input
637 clock frequency is not defined in the device tree, the macro
638 CONFIG_SYS_NS16550_CLK defined in a legacy board header file will

646 Enable this option to allow device-tree control of the driver.
647
648 Normally this driver is controlled by the following options:
649
650 CONFIG_SYS_NS16550_PORT_MAPPED - indicates that port I/O is used for
651 access. If not enabled, then the UART is memory-mapped.
652 CONFIG_SYS_NS16550_MEM32 - if memory-mapped, indicates that 32-bit
653 access should be used (instead of 8-bit)
654 CONFIG_SYS_NS16550_REG_SIZE - indicates register width and also
655 endianness. If positive, big-endian access is used. If negative,
656 little-endian is used.
657
658 It is not a good practice for a driver to be statically configured,
659 since it prevents the same driver being used for different types of
660 UARTs in a system. This option avoids this problem at the cost of a
661 slightly increased code size.
