1board/neo1973/bootmenu.c: simple configurable boot menu
2board/neo1973/neo1973.c (neo1973_new_second): return 1 if a new second has
3 started since the last call
4board/neo1973/neo1973.c (neo1973_on_key_pressed): return 1 if the $POWER key is
5 pressed
6board/neo1973/neo1973.c (board_late_init): make use of neo1973_new_second and
7 neo1973_on_key_pressed
8board/neo1973/neo1973.h: added function prototypes
9u-boot/board/neo1973/neo1973.c (board_late_init): enter the boot menu when
10 "AUX" was pressed at least half the time
11u-boot/board/neo1973/neo1973.c (board_late_init): minor code cleanup
12u-boot/common/console.c, include/console.h: added "console_poll_hook" to be
13 called when waiting for console in put in "getc" and "tstc"
14board/neo1973/neo1973.c (board_late_init): poll for the boot menu also on RAM
15 boot, reset, or unknown cause
16board/neo1973/neo1973.c (board_late_init): don't look for the power key if
17 woken up by the charger
