From 5bb78269000cf326bfdfa19f79449c02a9158020 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sun, 11 Sep 2005 22:30:22 +0200 Subject: kbuild: rename prepare to archprepare to fix dependency chain When introducing the generic asm-offsets.h support the dependency chain for the prepare targets was changed. All build scripts expecting include/asm/asm-offsets.h to be made when using the prepare target would broke. With the limited number of prepare targets left in arch Makefiles the trivial solution was to introduce a new arch specific target: archprepare The dependency chain looks like this now: prepare | +--> prepare0 | +--> archprepare | +--> scripts_basic +--> prepare1 | +---> prepare2 | +--> prepare3 So prepare 3 is processed before prepare2 etc. This guaantees that the asm symlink, version.h, scripts_basic are all updated before archprepare is processed. prepare0 which build the asm-offsets.h file will need the actions performed by archprepare. The head target is now named prepare, because users scripts will most likely use that target, but prepare-all has been kept for compatibility. Updated Documentation/kbuild/makefiles.txt.
