From 66d857b08b8c3ed5c72c361f863cce77d2a978d7 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Tue, 22 Mar 2011 13:39:27 +1000 Subject: m68k: merge m68k and m68knommu arch directories There is a lot of common code that could be shared between the m68k and m68knommu arch branches. It makes sense to merge the two branches into a single directory structure so that we can more easily share that common code. This is a brute force merge, based on a script from Stephen King , which was originally written by Arnd Bergmann . > The script was inspired by the script Sam Ravnborg used to merge the > includes from m68knommu. For those files common to both arches but > differing in content, the m68k version of the file is renamed to > _mm. and the m68knommu version of the file is moved into the > corresponding m68k directory and renamed _no. and a small > wrapper file . is used to select between the two version. Files > that are common to both but don't differ are removed from the m68knommu > tree and files and directories that are unique to the m68knommu tree are > moved to the m68k tree. Finally, the arch/m68knommu tree is removed. > > To select between the the versions of the files, the wrapper uses > > #ifdef CONFIG_MMU > #include _mm. > #else > #include _no. > #endif On top of this file merge I have done a simplistic merge of m68k and m68knommu Kconfig, which primarily attempts to keep existing options and menus in place. Other than a handful of options being moved it produces identical .config outputs on m68k and m68knommu targets I tested it on. With this in place there is now quite a bit of scope for merge cleanups in future patches.
