2012-07-31Add support for appended device tree blobs for armMaxime Ripard
This patch adds support for the ARM-only appended device tree mechanism present in the kernel. This option allows to add at the end of the kernel image the device tree blob so that we can still boot device tree enabled kernels with old bootloaders. This patch also adds the needed logic to genereate such an image when building zImages or uImages, also adding the necessary parts to rebuild the uImage.

2012-07-31Rework support for the device treeMaxime Ripard
This patch introduces some support for device tree-enabled kernels. It replaces the former BR2_LINUX_KERNEL_DTS_FILE option that was microblaze-only, that was quite limited. This option was quite limited, first obviously because it was restricted to microblaze, but also because it targetted only external device tree source files, and allowed only to build simpleImages using the custom image name mechanism. This patch adds a much more generic one, that can work on basically every architecture that supports device tree. It allows to build both device tree source file that comes with the kernel source or to set the path to the device tree file to use so that one can use a custom device tree.

2012-07-31Revert "Microblaze: build kernel with device tree"Maxime Ripard
This is way too specific to microblaze-only. Remove this support to introduce a more generic way to do support device tree kernels. This reverts commit aaed42d15643e0cb64c96fa400a6097a19d19ef4.

2012-05-05linux: improve the 'make linux-*' special commandsThomas Petazzoni
This patch improves two things: * It makes sure that the linux-menuconfig and al. commands can be executed even if the user hasn't executed 'make' before. Until now, the commands were depending on the .configured stamp, which is not sufficient since the linux package has been converted to the GENTARGETS infrastructure. Instead, depend on the linux-configure phony target. * It makes sure that those commands are not available when the Linux package is not selected, just like we do for Barebox.

2012-03-18DOWNLOAD: change $1=DIRECTORY_URL, $2=FILE_NAME to $1=FULL_FILE_URL, ↵Alvaro G. M
$2=FILE_NAME This modifies the definition of DOWNLOAD to receive two arguments: the first one is the full URL of the file to download, whereas the second (and optional) is the name the file will have once downloaded. Same thing with the SOURCE_CHECK_WGET and SCP functions. All calls to these functions have been changed to the shortest form of the new API, except for toolchains acquisition. Since there is quite a number of different toolchains this call to DOWNLOAD is better set to the generic one. Signed-off-by: Alvaro G.

2011-11-11linux: add linux-update-config and linux-update-defconfig targetsThomas De Schampheleire
In analogy to build targets uclibc-update and busybox-update, add extra targets to copy the current configuration to the custom configuration file set in buildroot. These targets facilitate the work of developers adding support for a specific board. linux-update-config copies .config directly. linux-update-defconfig first creates a defconfig and copies that.

2011-09-27fs/initramfs: refactor with fs/cpioArnout Vandecappelle (Essensium/Mind)
An initramfs is in fact the same as a cpio archive, but embedded in the kernel.

2011-07-11linux: add support for 3.x and -rc versionsThomas Petazzoni
The assumption that all kernels are in http://www.kernel.org/pub/linux/kernel/v2.6/ is no longer true: versions 3.x are in separate directories. We now compute the directory name from the major and minor versions of the version provided by the user. This assumes that the 3.1 version will be in a /v3.1/ directory, which we don't know yet because the 3.1 cycle hasn't started yet. At the same time, we add support for the official -rcX versions. Patch tested by compiling 3.0-rc6, which Buildroot has successfully downloaded and built.

2011-07-11Improve TARGETS handling for bootloaders and kernelThomas Petazzoni
As the kernel and bootloaders do not use the normal BR2_PACKAGE_* Kconfig options, their target name was not automatically added to the global TARGETS variable. Each bootloader .mk and the linux.mk had to add their own target manually to TARGETS, and the package infrastructure was making tests on non-existing Kconfig variables. This commit improves the package infrastructure so that it looks at BR2_PACKAGE_<pkg> for packages, BR2_TARGET_<pkg> for bootloaders and at the special BR2_LINUX_KERNEL for the linux package. This allows to simplify a little bit the bootloaders and linux .mk files. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2010-12-22linux: don't force IPv6 configuration in kernelThomas Petazzoni
As per the discussion at http://lists.busybox.net/pipermail/buildroot/2010-December/040030.html, remove the bits that forced the IPv6 configuration in the kernel depending on the toolchain ability to support (or not) IPv6. You may have a toolchain with IPv6 support but still don't want to have IPv6 in your kernel. The only parameters we adjust in the kernel configuration are: * ARM EABI, since we got a lot of bug reports regarding misconfigured kernel compared to the ABI used by userspace applications. * initramfs, since its contents are generated by Buildroot itself Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2010-12-17linux: add KERNEL_ARCH_PATH to fix x86-specific issueThomas Petazzoni
Both i386 and x86_64 architectures are supported by the arch/x86 directory in the kernel. So, when we copy the kernel configuration file to arch/$(KERNEL_ARCH)/configs/, it does not work because arch/i386 and arch/x86_64 do not exist. So, we introduce KERNEL_ARCH_PATH, which is the path to the architecture specific directory in the kernel source tree.

2010-12-16linux: support a space-separated list of patchesThomas Petazzoni
The kernel being a component that often needs a fairly important set of changes to be adapted to a particular hardware platform, having maximum flexibility on the patching process is a nice thing.

2010-12-16linux: Import minimal defconfigs as defconfigsThomas Petazzoni
Now that minimal kernel defconfigs are used in Buildroot, the problem is that copying those minimal configuration files to .config in the kernel source tree does not work, as kconfig will ask interactively what should be the value for all unspecified options. On suggestion on Sam Ravnborg, the easiest way to solve this is to import the minimal defconfig file as a defconfig inside the kernel tree (in arch/$(ARCH)/configs) and configure the kernel with it.

2010-12-11linux: restore DEPMOD usageMike Frysinger
The linux.mk rewrite lost the DEPMOD setting while installing modules which means depending on host-module-init-tools has been useless. Instead, the build system has been executing /sbin/depmod.
