Menu: add box style entry
this will allow you to create a box style entry via C API by specifying the type as struct menu_entry me = { .display "test", .type = MENU_ENTRY_BOX, .box_state = 1, .action = action_to_run, } and via shell menu -e -a -m <menu> -c <command> [-R] [-b 0|1] -d <description> menu -e -a -m <menu> -u submenu -d [-b 0|1] <description> -b with 0 for not selected and 1 for selected and -c for the command to run when changing state Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
