From 2a113281f5cd2febbab21a93c8943f8d3eece4d3 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sat, 10 Nov 2007 20:40:05 +0100 Subject: kconfig: use $K64BIT to set 64BIT with all*config targets The variable K64BIT can now be used to select the value of CONFIG_64BIT. This is for example useful for powerpc to generate allmodconfig for both bit sizes - like this: make ARCH=powerpc K64BIT=y make ARCH=powerpc K64BIT=n To use this the Kconfig file must use "64BIT" as the config value to select between 32 and 64 bit.
