Currently, packages that need the kernel to have support for laodable
modules have two ways to require it:
- either the use the kernel-module infra, which does it automatically,
- or they do not use it, and they need to require it manually by
setting the corresponding Makefile variable; however, they must only
set it when they are actually enabled, which makes for a slightly
cumbersome and ugly code, like:
ifeq ($(BR2_PACKAGE_FOO),y)
LINUX_NEEDS_MODULES = y
endif
Introduce a new blind Kconfig option that packages can select to signify
they need kernel modules. That Kconfig option is then used to set the
Makefile variable.
It makes it cleaner:
- code is simpler (one Kconfig line instead of a Makefile if-block,
- this is handled at the Kconfig level, which is where we usually
handle such dependencies.
Packages will be updated in follow-up commits.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
