2006-02-10[PATCH] Fix building external modules on ppc32Andreas Gruenbacher
We are setting up sources for building external modules like this: /usr/src/linux-obj> # create a .config file /usr/src/linux-obj> make -C /usr/src/linux O=$PWD oldconfig /usr/src/linux-obj> make -C /usr/src/linux O=$PWD prepare /usr/src/linux-obj> make -C /usr/src/linux O=$PWD scripts /usr/src/linux-obj> make -C /usr/src/linux O=$PWD clean After that, external modules can be built with: /usr/src/module> make -C /usr/src/linux-obj M=$PWD This fails for ppc32 because the `make clean' removes the arch/powerpc/include directory. This should be done in archmrproper instead of in archclean.

2006-02-10[PATCH] powerpc: Add CONFIG_DEFAULT_UIMAGE for embedded boardsKumar Gala
Embedded boards that u-boot require a kernel image in the uImage format. This allows a given board to specify it wants a uImage built by default. This also fixes a warning at config time, as this symbol is referred to in arch/powerpc/platforms/83xx/Kconfig.

2006-02-10[PATCH] powerpc: Add missing vmlinux.bin targetGeoff Levand
With this patch 'make vmlinux.bin' works. This is needed by some embedded platforms. Kumar already added the routines to actually build the image in arch/powerpc/boot/Makefile. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-01-13[PATCH] powerpc/boot: Better use of defaultimage-Tom Rini
The following reworks how defaultimage- is used. We default to zImage here and then override it on platforms that need something more (uImage in the future) or less (vmlinux on iSeries). Signed-off-by: Tom Rini <trini@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-13[PATCH] Remove bzImage targetTom Rini
Since the documentation no longer tells people to 'make bzImage', and with the previous patch nothing more than 'make' is required to get the right bootable images (just like on i386 now), this removes the bzImage -> zImage target redirect on ARCH=powerpc Signed-off-by: Tom Rini <trini@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-01-09[PATCH] powerpc: Add support for building uImagesKumar Gala
powerpc: Add support for building uImages Add support to build a kernel image bootable by u-boot. Most of the makefile foo is taken from arch/ppc/boot/images/Makefile Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-08kbuild: remove GCC_VERSIONSam Ravnborg
This was causing some ordering problems. Remove the up-front evaluation and just revaluate the compiler version each time we need it. (The up-front evaluation was problematic because some architectures modify the value of $(CC)). Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2005-11-25[PATCH] powerpc: remove arch/powerpc/include hack for 64 bitStephen Rothwell
With the removal of include/asm-powerpc, we no longer need arch/powerpc/include/asm for the 64 bit build. We also do not need -Iarch/powerpc for the 64 bit build either. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-18powerpc: Move defconfig over and remove remaining arch/ppc64 filesPaul Mackerras
make defconfig will now use arch/powerpc/configs/ppc64_defconfig if running on a ppc64 system. I need to add an arch/powerpc/configs/ppc_defconfig sometime. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-18powerpc: Move remaining .c files from arch/ppc64 to arch/powerpcPaul Mackerras
This also deletes the now-unused Makefiles under arch/ppc64. Both of the files moved over could use some merging, but for now I have moved them as-is and arranged for them to be used only in 64-bit kernels. For 32-bit kernels we still use arch/ppc/kernel/idle.c and drivers/char/generic_nvram.c as before. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-16powerpc: Move ppc64 boot wrapper code over to arch/powerpcPaul Mackerras
This also extends the code to handle 32-bit ELF vmlinux files as well as 64-bit ones. This is sufficient for booting on new-world 32-bit powermacs (i.e. all recent machines). Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-14[PATCH] powerpc: Always rebuild arch/powerpc/include/asm symlinkBenjamin Herrenschmidt
This patch uses a FORCE dependency on the arch/powerpc/include/asm symlink so that it always gets rebuilt, thus avoiding all sort of funny errors if the .config is changed between 32 and 64 bits. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-03powerpc: Set entry point and text address in linker scriptMichael Ellerman
Currently we set the kernel entry point and the address of the text section in the Makefile, using CONFIG_KERNEL_START. But we've already got <asm/page.h> in the linker script, so we can just use KERNELBASE directly. That means if we ever change KERNELBASE there's one less place to change it. And we can set the entry point with ENTRY(). There are zero differences from "readelf -a vmlinux" with or without this patch. Signed-off-by: Michael Ellerman <michael@ellerman.id.au>

Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-28powerpc: Merge xmonPaul Mackerras
The merged version follows the ppc64 version pretty closely mostly, and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version. The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state'). Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20ppc64: Minor compilation fixesPaul Mackerras
This defines CONFIG_PPC_STD_MMU for ppc64, changes an instance of sys32_ to compat_sys_ in the ppc64 syscall table, and removes a reference to a non-existent arch/powerpc/xmon/Makefile. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-18powerpc: Fix various compile errors with ARCH=ppc, ppc64 and powerpcPaul Mackerras
This makes ppc use the syscalls.c from arch/powerpc/kernel, exports copy_and_flush from head_32.S for use by prom_init.c (ARCH=powerpc), and consolidates the sys_fadvise64_64 implementations for 32-bit. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-13powerpc: fix uname -mStephen Rothwell
It will now give ppc64 on 64bit platforms and ppc on 32bit platforms. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-11powerpc: Make building the boot image work for both 32-bit and 64-bitPaul Mackerras
At the moment we don't have a merged arch/powerpc/boot, so we build the boot images in arch/ppc/boot and arch/ppc64/boot. Unfortunately the makefile targets are different in those two directories, so this makes a change to accommodate both for the moment. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.SPaul Mackerras
The system call table has been consolidated into systbl.S. We have separate 32-bit and 64-bit versions of entry.S and misc.S since the code is mostly sufficiently different to be not worth merging. There are some common bits that will be extracted in future. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Use arch/powerpc/mm and arch/powerpc/lib for 64-bitPaul Mackerras
This also puts a copy of indirect_pci.c in arch/powerpc/sysdev so that we don't need to build in arch/ppc/syslib. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Rename files to have consistent _32/_64 suffixesPaul Mackerras
This doesn't change any code, just renames things so we consistently have foo_32.c and foo_64.c where we have separate 32- and 64-bit versions. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-01powerpc: make iSeries buildStephen Rothwell

2005-09-26powerpc: Merge enough to start building in arch/powerpc.Paul Mackerras
This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting.
