Hi Grant
Humm, do i have an old version of ePAPR?
All i see is that in Table 3-4 It says:
stdout-path O <string> A string that specifies the full path to the node representing the device to be used for boot console output. If the character ":" is present in the value it terminates the path. The value may be an alias.
If the stdin-path property is not specified, stdout-path should be assumed to define the input device.
So what is before the : is defined. What comes afterwards, baudrate/parity/bits/flow control does not appear to the defined in ePAPR. Should we not document the extension being added here?
Andrew
