From 928923c76b393e38e5ba1d47e843e208ceef6cf9 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 22 Aug 2007 14:01:36 -0700 Subject: [PATCH] Introduce CONFIG_CHECK_SIGNATURE Introduce CONFIG_CHECK_SIGNATURE to control inclusion of check_signature() and avoid problems on platforms that don't have readb(). Let the few legacy (ISA || PCI || X86) drivers that need check_signature() select CONFIG_CHECK_SIGNATURE.
