description:
|
|
The Aspeed UART routing control allow to dynamically route the inputs for
|
|
the built-in UARTS and physical serial I/O ports.
|
|
|
|
This allows, for example, to connect the output of UART to another UART.
|
|
This can be used to enable Host <-> BMC communication via UARTs, e.g. to
|
|
allow access to the Host's serial console.
|
|
|
|
This driver is for the BMC side. The sysfs files allow the BMC userspace
|
|
which owns the system configuration policy, to configure how UARTs and
|
|
physical serial I/O ports are routed.
