* kbuild: generate modules.builtinMichal Marek2009-12-12
| | | | | | | | | | | To make it easier for module-init-tools and scripts like mkinitrd to distinguish builtin and missing modules, install a modules.builtin file listing all builtin modules. This is done by generating an additional config file (tristate.conf) with tristate options set to uppercase 'Y' or 'M'. If we source that config file, the builtin modules appear in obj-Y.

* kbuild: use INSTALLKERNEL to select customized installkernel scriptSam Ravnborg2009-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* kconfig: resort the documentation of the environment variablesMarkus Heidelberg2009-06-09
| | | | | | | | | | | | | | | | | 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'".

* kbuild: introduce subdir-ccflags-ySam Ravnborg2009-04-19
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Introduce ccflags-y, asflags-y and ldflags-y so we soon can deprecate use of EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS. This patch does not touch any in-tree users - thats next round. Lets get this committed first and then fix the users of the soon to be deprecated variants next. The rationale behind this change is to introduce support for makefile fragments like: ccflags-$(CONFIG_WHATEVER_DEBUG) := -DDEBUG As a replacement for the uglier: ifeq ($(CONFIG_WHATEVER_DEBUG),y) EXTRA_CFLAGS := -DDEBUG endif Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
