From 53892de14c1a5fb76f0e342428aafa6e6932062a Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN\"" Date: Sun, 8 May 2011 19:02:44 +0200 Subject: config: fix recursive deps The latest kconfig stuff is more stringent when it comes to validating the dependency of the symbols. It is no longer possible to have a symbol depend on itself (such as our construct for arch/cc/libc/... was doing). Fix our generated-file infrastructure to avoid these situations when the new kconfig stuff will be merged (in a following changeset). Signed-off-by: "Yann E. MORIN" diff --git a/config/arch/alpha.in b/config/arch/alpha.in index 387d355..f0c6b95 100644 --- a/config/arch/alpha.in +++ b/config/arch/alpha.in @@ -1,10 +1,9 @@ # Alpha specific configuration file -config ARCH_alpha -
