Message:

Replace the "vci_mlti_tty" component by the "vci_tty_tsar" component,
in yje tsar_generic_iob platform.
This new component povide two IRQs per channel:

  • RX_IRQ, when the read buffer is non-empty
  • TX_IRQ, when the write buffer is not full.

The new tsar_generic_iob platform supports up to 8 TTY channels.
The new vci_tty_tsar component is stored in the TSAR SVN.
