[PATCH 1/5] tty: serial: sh-sci: Hide number of ports config question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Auto-configure the maximum number of serial ports based on how many can
be present on the architecture:
  - 3 on H8/300,
  - 10 on SuperH,
  - 18 on Reneas ARM.

The default can still be overridden if CONFIG_EXPERT is enabled.
