[U-Boot] [PATCH 11/15] New config variable CONFIG_MENUCMD

Pali Rohár pali.rohar at gmail.com
Sun Dec 18 22:34:07 CET 2011


 * If not defined CONFIG_MENUCMD do nothing

 * If CONFIG_MENUKEY is 0 and was pressed any key run env "menu_cmd"
 * If pressed key was CONFIG_MENUKEY run env "menu_cmd"
 * If CONFIG_MENUKEY is not defined run env "menu_cmd" always

 * CONFIG_MENUKEY working if defined CONFIG_MENUCMD and CONFIG_BOOTDELAY >= 0
