From 8ea13e2c87c83b7cb0b360cb8779415967727647 Mon Sep 17 00:00:00 2001 From: Arnaud Lacombe Date: Mon, 16 Aug 2010 22:55:31 -0400 Subject: kconfig: implement the `mainmenu' directive If specified, the directive must be placed at the top of the Kconfig file. We need to change the grammar to make the mainmenu directive set the `rootmenu' prompt. This reflect how menu_add_prompt() works internally, ie. set the prompt of the `current_entry', pointing originally to `rootmenu'.
