arch/h8300: add a defconfig target Make the "defconfig" target valid for arch/h8300. Currently "make ARCH=h8300 defconfig" produces: *** Can't find default configuration "arch/h8300/defconfig"! ../scripts/kconfig/Makefile:87: recipe for target 'defconfig' failed By adding a value for KBUILD_DEFCONFIG, "make ARCH=h8300 defconfig" successfully produces a kernel .config file: *** Default configuration is based on 'edosk2674_defconfig' This is useful for Kconfig editing/testing.

kbuild: rename LDFLAGS to KBUILD_LDFLAGS 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 <yamada.masahiro@socionext.com> Acked-by: Kirill A.

h8300:let the checker know that size_t is ulong All 64bit archs use unsigned long for size_t and most 32bit archs use 'unsigned int'. By default, this is what is assumed by sparse. However, on h8300 (a 32bit arch) size_t is unsigned long which can led sparse to emit wrong warnings. Fix this by passing to sparse the flag -msize-long, telling it that size_t is unsigned long.

h8300: Don't set CROSS_COMPILE unconditionally The h8300 architecture Makefile sets the CROSS_COMPILE variable to "h8300-unknown-linux-" unconditionally but doing that prevents the variable to be used if a toolchain with a different binary name is installed in the machine. So only set CROSS_COMPILE to that default if the variable has not been set by the user before. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com>

h8300: use cc-cross-prefix instead of hardcoding h8300-unknown-linux- It believe it is a bad idea to hardcode a specific compiler prefix that may or may not be installed on a user's system. It is annoying when testing features that should not require compilers at all. For example, mrproper, headers_install, etc. should work without any compiler. They look like follows on my machine. $ make ARCH=h8300 mrproper ./scripts/gcc-version.sh: line 26: h8300-unknown-linux-gcc: command not found ./scripts/gcc-version.sh: line 27: h8300-unknown-linux-gcc: command not found make: h8300-unknown-linux-gcc: Command not found make: h8300-unknown-linux-gcc: Command not found [ a bunch of the same error messages continue ] $ make ARCH=h8300 headers_install ./scripts/gcc-version.sh: line 26: h8300-unknown-linux-gcc: command not found ./scripts/gcc-version.sh: line 27: h8300-unknown-linux-gcc: command not found make: h8300-unknown-linux-gcc: Command not found HOSTCC scripts/basic/fixdep make: h8300-unknown-linux-gcc: Command not found WRAP arch/h8300/include/generated/uapi/asm/kvm_para.h [ snip ] The solution is to delete this line, or to use cc-cross-prefix like some architectures do. I chose the latter as a moderate fixup. I added an alternative 'h8300-linux-' because it is available at: https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/ Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
