PR 349/bsps

  • console/console.c, console/uart.c, console/uart.h: implement IOCTLs for the serial (UART) console to install/retrieve a BREAK-IRQ callback. The callback routine (if installed) is invoked from the UART ISR when a BREAK interrupt is detected. This can be used e.g. to enforce a "hotkey" reboot a la vxWorks Ctrl-X (although we use the serial line break condition) NOTE: The callback runs in ISR context.
  • Property mode set to 100644
