2011-03-09kbuild: Add extra gcc checksBorislav Petkov
Add a 'W=1' Makefile switch which adds additional checking per build object. The idea behind this option is targeted at developers who, in the process of writing their code, want to do the occasional make W=1 [target.o] and let gcc do more extensive code checking for them. Then, they could eyeball the output for valid gcc warnings about various bugs/discrepancies which are not reported during the normal build process.

2010-12-23of: Add support for linking device tree blobs into vmlinuxDirk Brandewie
This patch adds support for linking device tree blob(s) into vmlinux. Modifies asm-generic/vmlinux.lds.h to add linking .dtb sections into vmlinux. To maintain compatiblity with the of/fdt driver code platforms MUST copy the blob to a non-init memory location before the kernel frees the .init.* sections in the image. Modifies scripts/Makefile.lib to add a kbuild command to compile DTS files to device tree blobs and a rule to create objects to wrap the blobs for linking. STRUCT_ALIGNMENT is defined in vmlinux.lds.h for use in the rule to create wrapper objects for the dtb in Makefile.lib. The STRUCT_ALIGN() macro in vmlinux.lds.h is modified to use the STRUCT_ALIGNMENT definition. The DTB's are placed on 32 byte boundries to allow parsing the blob with driver/of/fdt.c during early boot without having to copy the blob to get the structure alignment GCC expects. A DTB is linked in by adding the DTB object to the list of objects to be linked into vmlinux in the archtecture specific Makefile using obj-y += foo.dtb.o Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com> Acked-by: Michal Marek <mmarek@suse.cz> [grant.likely@secretlab.ca: cleaned up whitespace inconsistencies] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

Usefull if building for sparc64 userland, because the sparc and sparc64 userlands use the same 64-bit kernel, making it impossible to always select the correct userland architecture for the resulting debian package.

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.

2009-09-20kbuild: use INSTALLKERNEL to select customized installkernel scriptSam Ravnborg
Replace the use of CROSS_COMPILE to select a customized installkernel script with the possibility to set INSTALLKERNEL to select a custom installkernel script when running make: make INSTALLKERNEL=arm-installkernel install With this patch we are now more consistent across different architectures - they did not all support use of CROSS_COMPILE. The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

2009-06-09kconfig: resort the documentation of the environment variablesMarkus Heidelberg
All the KCONFIG_ environment variables were previously located in a section "Environment variables in 'menuconfig'", but neither are they restricted to 'menuconfig' nor are they all used by 'menuconfig'. Introduce the following three sections for these variables: * Environment variables for '*config' * Environment variables for '{allyes/allmod/allno/rand}config' * Environment variables for 'silentoldconfig' Furthermore this puts MENUCONFIG_MODE next to MENUCONFIG_COLOR into a common section "User interface options for 'menuconfig'".

2009-04-19kbuild: introduce subdir-ccflags-ySam Ravnborg
Following patch introduce support for setting options to gcc that has effect for current directory and all subdirectories. The typical use case are an architecture or a subsystem that decide to cover all files with -Werror. Today alpha, mips and sparc uses -Werror in almost all their Makefile- with subdir-ccflag-y it is now simpler to do so as only the top-level directories needs to be covered. Likewise if we decide to cover a full subsystem such as net/ with -Werror this is done by adding a single line to net/Makefile.
