-- General:
-
-               In the target system modem support is enabled when a
-               specific key (key combination) is pressed during
-               power-on. Otherwise U-Boot will boot normally
-               (autoboot). The key_pressed() function is called from
-               board_init(). Currently key_pressed() is a dummy
-               function, returning 1 and thus enabling modem
-               initialization.
-
-               If there are no modem init strings in the
-               environment, U-Boot proceed to autoboot; the
-               previous output (banner, info printfs) will be
-               suppressed, though.
