commit 3e02d519d5e535af8c73a56e9233fb289c6b4b8f Author: Roman Zippel zippel@linux-m68k.org Date: Fri Feb 29 05:11:50 2008 +0100
kconfig: add named choice group
As choice dependency are now fully checked, it's quite easy to add support for named choices. This lifts the restriction that a choice value can only appear once, although it still has to be within the same group, but multiple choices can be joined by giving them a name. While at it I cleaned up a little the choice type logic to simplify it a bit.
