From 2ef9f59a7a3a0894be63836542f0902a45ffdd22 Mon Sep 17 00:00:00 2001 From: Jean-Christophe PLAGNIOL-VILLARD Date: Thu, 22 Oct 2009 18:50:26 +0200 Subject: at91: Kconfig simplification Instead of adding "depends on" at config level, introduce HAVE_* config variables. Add them at machine or soc level to specify the ability of a particular support. It will ease new board introduction and readability.
