config 16550_SERIAL_DISABLE_REORDERING
bool "Disable reordering of ttySx devices."
default n
---help---
NuttX per default reorders the serial ports (/dev/ttySx) so that the
console is always on /dev/ttyS0. If more than one UART is in use this
can, however, have the side-effect that all port mappings
(hardware USART1 -> /dev/ttyS0) change if the console is moved to another
UART. This option disables that re-ordering for 16550 UARTs.
