- help
- The debug UART is intended for use very early in U-Boot to debug

- To use it you should:
- - Make sure your UART supports this interface
- - Enable CONFIG_DEBUG_UART
- - Enable the CONFIG for your UART to tell it to provide this interface
- (e.g. CONFIG_DEBUG_UART_NS16550)
- - Define the required settings as needed (see below)
- - Call debug_uart_init() before use
- - Call debug_uart_putc() to output a character
- Depending on your platform it may be possible to use this UART before
- a stack is available.
- If your UART does not support this interface you can probably add
- support quite easily. Remember that you cannot use driver model and
- it is preferred to use no stack.
- You must not use this UART once driver model is working and the
- serial drivers are up and running (done in serial_init()). Otherwise
- the drivers may conflict and you will get strange output.

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

- bool "Allow NS16550 to be configured at runtime"
- default y if SYS_COREBOOT || SYS_SLIMBOOTLOADER
- help
- Enable this option to allow device-tree control of the driver.
- Normally this driver is controlled by the following options:
- CONFIG_SYS_NS16550_PORT_MAPPED - indicates that port I/O is used for
- access. If not enabled, then the UART is memory-mapped.
- CONFIG_SYS_NS16550_MEM32 - if memory-mapped, indicates that 32-bit
- access should be used (instead of 8-bit)
- CONFIG_SYS_NS16550_REG_SIZE - indicates register width and also
- endianness. If positive, big-endian access is used. If negative,
- little-endian is used.
- It is not a good practice for a driver to be statically configured,
- since it prevents the same driver being used for different types of
- UARTs in a system. This option avoids this problem at the cost of a
- slightly increased code size.

- help
- Select this to enable a seral UART for sandbox. This is required to

- sandbox. The emulated UART will display to the console and console
- input will be fed into the UART. This allows you to interact with
- U-Boot.
- The operation of the console is controlled by the -t command-line
- flag. In raw mode, U-Boot sees all characters from the terminal
- before they are processed, including Ctrl-C. In cooked mode, Ctrl-C
- is processed by the terminal, and terminates U-Boot. Valid options
- are:
- -t raw-with-sigs Raw mode, Ctrl-C will terminate U-Boot
