     7// The tty_driver.c and tty_drivers.h files are part ot the GIET-VM kernel.
     8// This driver supports the SocLib vci_multi_tty component.
     9//
     10// The total number of TTY terminals must be defined by the configuration
     11// parameter NB_TTY_CHANNELS in the hard_config.h file.
     12//
     13// The "system" terminal is TTY[0].
     14// The "user" TTYs are allocated to applications requesting it.
     15//
     16// The SEG_TTY_BASE address must be defined in the hard_config.h file.
     17//
     18// All physical accesses to device registers are done by the two
     19// _tty_get_register(), _tty_set_register() low-level functions,
     20// that are handling virtual / physical addressing.
