* linux: Install the device tree in /boot when installing the kernelMaxime Ripard2013-02-191-0/+8
| | | | | | | | | | | The option BR2_LINUX_KERNEL_INSTALL_TARGET used to install the kernel in /boot in the rootfs. The introduction of the device tree builds made it possible to generate device tree blobs, and stored them in IMAGES_DIR like the kernel, but didn't copy the dtb in /boot when _INSTALL_TARGET was enabled.

* linux, uboot, mxs-bootlets, barebox: avoid double slash in CUSTOM_TARBALLArnout Vandecappelle (Essensium/Mind)2013-01-131-1/+1
| | | | | | | | | | | | | | | Closes #5846 The $(dir ...) function leaves a slash at the end, so that the LINUX_SITE variable for a custom tarball ends in a slash. The DOWNLOAD macro adds another slash between SITE and SOURCE, which results in a double slash in the download URL. Fix this by stripping off the final slash from the _SITE in all packages that have a custom tarball.

* Add support for appended device tree blobs for armMaxime Ripard2012-07-311-1/+36
| | | | | | | | | | | | | | | | 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.

* Rework support for the device treeMaxime Ripard2012-07-311-0/+19
| | | | | | | | | | | | | | | | | | | | | 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.

* linux: improve the 'make linux-*' special commandsThomas Petazzoni2012-05-051-3/+5
| | | | | | | | | | | | | | | | | 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.

* DOWNLOAD: change $1=DIRECTORY_URL, $2=FILE_NAME to $1=FULL_FILE_URL, ↵Alvaro G. M2012-03-181-1/+1
| | | | | | | | | | | | | | | | | | | | | $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.

* linux: add support for 3.x and -rc versionsThomas Petazzoni2011-07-111-1/+10
| | | | | | | | | | | | | | | | | | | 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.

* Improve TARGETS handling for bootloaders and kernelThomas Petazzoni2011-07-111-5/+0
| | | | | | | | | | | | | | | | | | 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>

You may have a toolchain with IPv6 support but still don't want to have IPv6 in your kernel.
