kbuild: rebuild modules when module linker scripts are updated

2019-08-21T12:05:21Z

Currently, the timestamp of module linker scripts are not checked. Add them to the dependency of modules so they are correctly rebuilt. Signed-off-by: Masahiro Yamada

m68k: Add -ffreestanding to CFLAGS

2019-01-21T09:36:53Z

This patch fixes a build failure when using GCC 8.1: /usr/bin/ld: block/partitions/ldm.o: in function `ldm_parse_tocblock': block/partitions/ldm.c:153: undefined reference to `strcmp' This is caused by a new optimization which effectively replaces a strncmp() call with a strcmp() call. This affects a number of strncmp() call sites in the kernel. The entire class of optimizations is avoided with -fno-builtin, which gets enabled by -ffreestanding. This may avoid possible future build failures in case new optimizations appear in future compilers. I haven't done any performance measurements with this patch but I did count the function calls in a defconfig build. For example, there are now 23 more sprintf() calls and 39 fewer strcpy() calls. The effect on the other libc functions is smaller. If this harms performance we can tackle that regression by optimizing the call sites, ideally using semantic patches. That way, clang and ICC builds might benfit too.

m68k: Generate uapi header and syscall table header files

2018-12-04T08:47:55Z

System call table generation script must be run to gener- ate unistd_32.h and syscall_table.h files. This patch will have changes which will invokes the script. This patch will generate unistd_32.h and syscall_table.h files by the syscall table generation script invoked by m68k/Makefile and the generated files against the removed files must be identical. The generated uapi header file will be included in uapi/- asm/unistd.h and generated system call table header file will be included by kernel/syscalltable.S file.

kbuild: rename LDFLAGS to KBUILD_LDFLAGS

2018-08-23T23:22:08Z

Commit a0f97e06a43c ("kbuild: enable 'make CFLAGS=...' to add additional options to CC") renamed CFLAGS to KBUILD_CFLAGS. Commit 222d394d30e7 ("kbuild: enable 'make AFLAGS=...' to add additional options to AS") renamed AFLAGS to KBUILD_AFLAGS. Commit 06c5040cdb13 ("kbuild: enable 'make CPPFLAGS=...' to add additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS. For some reason, LDFLAGS was not renamed. Using a well-known variable like LDFLAGS may result in accidental override of the variable. Kbuild generally uses KBUILD_ prefixed variables for the internally appended options, so here is one more conversion to sanitize the naming convention. I did not touch Makefiles under tools/ since the tools build system is a different world. Signed-off-by: Masahiro Yamada Acked-by: Kirill A. Shutemov Reviewed-by: Palmer Dabbelt

m68knommu: remove obsolete 68360 support

2016-03-07T00:07:17Z

Remove the obsolete Motorola/Freescale 68360 SoC support. It has been bit rotting for many years with little active use in mainlne. There has been no serial driver support for many years, so it is largely not useful in its current state. Signed-off-by: Greg Ungerer

m68k: move non-mmu 68360 platform code

2014-09-28T23:18:35Z

The non-mmu 68360 specific code is inconsistently placed under a directory named "platform". Move it to arch/m68k/ along with the other platform and board directories. Signed-off-by: Greg Ungerer Acked-by: Geert Uytterhoeven

m68k: move non-mmu 68000 platform code

m68k: move coldfire platform code

2014-09-28T23:18:34Z

Move the m68k ColdFire platform support code directory to be with the existing m68k platforms. Although the ColdFire is not a platform as such, we have always kept all its support together. No reason to change that as this time. Signed-off-by: Greg Ungerer Acked-by: Geert Uytterhoeven

m68knommu: add support for the ColdFire 537x family of CPUs

2013-04-28T23:17:58Z

The ColdFire 537x family is very similar internally to the ColdFire 532x family. So with just a little extra configuration we can configure and target them as well. Signed-off-by: Greg Ungerer

m68knommu: platform code merge for 68000 core cpus

2012-12-05T00:48:47Z

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 Signed-off-by: Greg Ungerer
