2023-07-05sh: Remove compiler flag duplicationMasahiro Yamada1-3/+1
Every compiler flag added by arch/sh/Makefile is passed to the compiler twice: $(KBUILD_CPPFLAGS) + $(KBUILD_CFLAGS) is used for compiling *.c $(KBUILD_CPPFLAGS) + $(KBUILD_AFLAGS) is used for compiling *.S Given the above, adding $(cflags-y) to all of KBUILD_{CPP/C/A}FLAGS ends up with duplication. Add -I options to $(KBUILD_CPPFLAGS), and the rest of $(cflags-y) to KBUILD_{C,A}FLAGS.

2023-07-05sh: Fix -Wmissing-include-dirs warnings for various platformsMasahiro Yamada1-17/+1
The 0day bot reports a lot of warnings (or errors due to CONFIG_WERROR) like this: cc1: error: arch/sh/include/mach-hp6xx: No such file or directory [-Werror=missing-include-dirs] Indeed, arch/sh/include/mach-hp6xx does not exist. While -Wmissing-include-dirs is only a W=1 warning, it may be annoying when CONFIG_BTRFS_FS is enabled because fs/btrfs/Makefile unconditionally adds this warning option. arch/sh/Makefile defines machdir-y for two purposes: - Build platform code in arch/sh/boards/mach-*/ - Add arch/sh/include/mach-*/ to the header search path For the latter, some platforms use arch/sh/include/mach-common/ instead of having its own arch/sh/include/mach-*/. Drop unneeded machdir-y to omit non-existing include directories. To build arch/sh/boards/mach-*/, use the standard obj-y syntax in arch/sh/boards/Makefile.

2022-10-02kbuild: remove head-y syntaxMasahiro Yamada1-2/+0
Kbuild puts the objects listed in head-y at the head of vmlinux. Conventionally, we do this for head*.S, which contains the kernel entry point. A counter approach is to control the section order by the linker script. Actually, the code marked as __HEAD goes into the ".head.text" section, which is placed before the normal ".text" section. I do not know if both of them are needed. From the build system perspective, head-y is not mandatory. If you can achieve the proper code placement by the linker script only, it would be cleaner. I collected the current head-y objects into head-object-list.txt. It is a whitelist. My hope is it will be reduced in the long run.

2021-10-24kbuild: use more subdir- for visiting subdirectories while cleaningMasahiro Yamada1-3/+0
Documentation/kbuild/makefiles.rst suggests to use "archclean" for cleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement. Since commit d92cc4d51643 ("kbuild: require all architectures to have arch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick for all architectures. This can take advantage of the parallel option (-j) for "make clean". I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep" target no longer exists.

2021-05-06arch: use cross_compiling to check whether it is a cross build or notMasahiro Yamada1-1/+1
'cross_compiling' is defined by the top Makefile and available for arch Makefiles to check whether it is a cross build or not. A good thing is the variable name 'cross_compiling' is self-documenting. This is a simple replacement for m68k, mips, sh, for which $(ARCH) and $(SRCARCH) always match. No functional change is intended for xtensa, either. This is rather a fix for parisc because arch/parisc/Makefile defines UTS_MATCHINE depending on CONFIG_64BIT, therefore cc-cross-prefix is not working in Kconfig time.

2019-05-18treewide: prefix header search paths with $(srctree)/Masahiro Yamada1-2/+2
Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks.

2018-08-24kbuild: rename LDFLAGS to KBUILD_LDFLAGSMasahiro Yamada1-2/+2
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.

2017-11-13sh: select KBUILD_DEFCONFIG depending on ARCHMasahiro Yamada1-2/+6
You can not select KBUILD_DEFCONFIG depending on any CONFIG option because include/config/auto.conf is not included when building config targets. So, CONFIG_SUPERH32 is never set during the configuration, then cayman_defconfig is always chosen. This commit provides a sensible way to choose shx3/cayman_defconfig. arch/sh/Kconfig sets either SUPERH32 or SUPERH64 depending on ARCH environment, like follows: config SUPERH32 def_bool ARCH = "sh" ... config SUPERH64 def_bool ARCH = "sh64" It should make sense to choose the default defconfig by ARCH, like arch/sparc/Makefile.

Signed-off-by: Rich Felker <dalias@libc.org>
2016-08-05sh: add support for J-Core J2 processorRich Felker1-0/+1
At the CPU/ISA level, the J2 is compatible with SH-2, and thus the changes to add J2 support build on existing SH-2 support. However, J2 does not duplicate the memory-mapped SH-2 features like the cache interface. Instead, the cache interfaces is described in the device tree, and new code is added to be able to access the flat device tree at early boot before it is unflattened. Support is also added for receiving interrupts on trap numbers in the range 16 to 31, since the J-Core aic1 interrupt controller generates these traps. This range was unused but nominally for hardware exceptions on SH-2, and a few values in this range were used for exceptions on SH-2A, but SH-2A has its own version of the relevant code. No individual cpu subtypes are added for J2 since the intent moving forward is to represent SoCs with device tree rather than as hard-coded subtypes in the kernel. The CPU_SUBTYPE_J2 Kconfig item exists only to fit into the existing cpu selection mechanism until it is overhauled. Signed-off-by: Rich Felker <dalias@libc.org>

2014-07-23sh: also try passing -m4-nofpu for SH2A buildsGeert Uytterhoeven1-1/+2
When compiling a SH2A kernel (e.g. se7206_defconfig or rsk7203_defconfig) using sh4-linux-gcc, linking fails with: net/built-in.o: In function `__sk_run_filter': net/core/filter.c:566: undefined reference to `__fpscr_values' net/core/filter.c:269: undefined reference to `__fpscr_values' ... net/built-in.o:net/core/filter.c:580: more undefined references to `__fpscr_values' follow This happens because sh4-linux-gcc doesn't support the "-m2a-nofpu", which is thus filtered out by "$(call cc-option, ...)". As compiling using sh4-linux-gcc is useful for compile coverage, also try passing "-m4-nofpu" (which is presumably filtered out when using a real sh2a-linux toolchain) to disable the generation of FPU instructions and references to __fpscr_values[].
