2012-12-05m68knommu: platform code merge for 68000 core cpusLuis Alves
This patch merges all 68000 core cpus into one directory. There is a lot of common code in the 68328, 68EZ328 and 68VZ328 directories. This will also facilitate easy development of support for original stand alone MC68000 CPU machines. Signed-off-by: Luis Alves <ljalvs@gmail.com> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2012-07-16m68knommu: Add support for the Coldfire m5441x.Steven King
Add support for the Coldfire 5441x (54410/54415/54416/54417/54418). Currently we only support noMMU mode. It requires the PIT patch posted previously as it uses the PIT instead of the dma timer as a clock source so we can get all that GENERIC_CLOCKEVENTS goodness. It also adds some simple clk definitions and very simple minded power management. The gpio code is tweeked and some additional devices are added to devices.c. The Makefile uses -mv4e as apparently, the only difference a v4m (m5441x) and a v4e is the later has a FPU, which I don't think should matter to us in the kernel.

git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu Pull m68knommu tree from Greg Ungerer: "More merge and clean up of MMU and non-MMU common files, namely signal.c and dma.c. There is also a simplification of the ColdFire GPIO setup tables. Using a couple of simple macros we make the init tables really small and easy to read, and save a couple of thousand lines of code. Also a move of all the ColdFire subarch support files into the existing coldfire directory. The sub-directories just ended up duplicating Makefiles and now only contain really simple pieces of code. This saves quite a few lines of code too. As always a couple of bugs fixes thrown in too. Oh and a new defconfig for the ColdFire platforms that support having the MMU enabled." * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: (39 commits) m68k: add a defconfig for the M5475EVB ColdFire with MMU board m68knommu: unaligned.h fix for M68000 core m68k: merge the MMU and non-MMU versions of the arch dma code m68knommu: reorganize the no-MMU cache flushing to match m68k m68knommu: move the 54xx platform code into the common ColdFire code directory m68knommu: move the 532x platform code into the common ColdFire code directory m68knommu: move the 5407 platform code into the common ColdFire code directory m68knommu: move the 5307 platform code into the common ColdFire code directory m68knommu: move the 528x platform code into the common ColdFire code directory m68knommu: move the 527x platform code into the common ColdFire code directory m68knommu: move the 5272 platform code into the common ColdFire code directory m68knommu: move the 5249 platform code into the common ColdFire code directory m68knommu: move the 523x platform code into the common ColdFire code directory m68knommu: move the 520x platform code into the common ColdFire code directory m68knommu: move the 5206 platform code into the common ColdFire code directory m68knommu: simplify the ColdFire 5407 GPIO struct setup m68knommu: simplify the ColdFire 532x GPIO struct setup m68knommu: simplify the ColdFire 5307 GPIO struct setup m68knommu: simplify the ColdFire 528x GPIO struct setup m68knommu: simplify the ColdFire 527x GPIO struct setup ...

2012-05-16m68k: Setup CROSS_COMPILE at the topGeert Uytterhoeven
CROSS_COMPILE must be setup before using e.g. cc-option (and a few other as-*, cc-*, ld-* macros), else they will check against the wrong compiler when cross-compiling, and may invoke the cross compiler with wrong or suboptimal compiler options.

2011-10-18m68k: merge mmu and non-mmu arch MakefilesGreg Ungerer
Most of the build logic is the same for the mmu and non-mmu m68k targets. Merge the top level architecture Makefiles back into a single Makefile. For the most part this is just adding the non-mmu processor types and their specific cflags and other options into the mmu Makefile. Note that all the BOARD setting logic that was in the non-mmu Makefile is completely removed. It was no longer being used at all. This has been build and run tested on ColdFire targets and ARAnyM. It has been build tested on all the m68k defconfig targets using a gcc-4.5.1 based toolchain. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Sam Ravnborg <sam@ravnborg.org>
2011-03-25m68k: merge m68k and m68knommu arch directoriesGreg Ungerer
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 <sfking@fdwdc.com>, which was originally written by Arnd Bergmann <arnd@arndb.de>. > 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 > <file>_mm.<ext> and the m68knommu version of the file is moved into the > corresponding m68k directory and renamed <file>_no.<ext> and a small > wrapper file <file>.<ext> 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 <file>_mm.<ext> > #else > #include <file>_no.<ext> > #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. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2010-08-03kbuild: allow assignment to {A,C,LD}FLAGS_MODULE on the command lineSam Ravnborg
It is now possible to assign options to AS, CC and LD on the command line - which is only used when building modules. {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC, LD when building modules without overriding the original value. Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE that is used by arch specific files and free up {A,C,LD}FLAGS_MODULE so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated. Note: Previously we had a MODFLAGS variable for both AS and CC. But in favour of consistency this was dropped. So in some cases arch Makefile has one assignmnet replaced by two assignmnets. Note2: MODFLAGS was not documented and is dropped without any notice. I do not expect much/any breakage from this.

2007-10-14kbuild: enable 'make CFLAGS=...' to add additional options to CCSam Ravnborg
The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
