* linux: Do not force GZIP initramfs compressionValentine Barshak2013-07-081-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initramfs compression does not make much sense for the architectures that support compressed kernel images because in this case the data would be compressed twice. This will eventually result in a bigger kernel image and time overhead when uncompressing it. The only reason to use compressed initramfs is to reduce memory usage when the kernel prepares rootfs, and both the unpacked filesystem and initramfs.cpio are present in the memory. Buildroot attempts to force GZIP compression for initramfs, however it doesn't always work because initramfs compression mode depends on RAM disk compression supported by the kernel. Thus, CONFIG_INITRAMFS_COMPRESSION_GZIP depends on CONFIG_RD_GZIP. If CONFIG_RD_GZIP is not set, setting GZIP initramfs compression will have no effect. Besides, the kernel also supports other compression methods, like BZIP2, LZMA, XZ and LZO. Forcing the good old GZIP does not really make much sense any more. This removes initramfs compression settings from Buildroot, so that the default value preset in the kernel config is used, which is CONFIG_INITRAMFS_COMPRESSION_NONE. If initramfs compression is still needed, it can be set in the kernel config (using make linux-menuconfig) Signed-off-by: Valentine Barshak <gvaxon@gmail.com> Acked-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

| | | | | | | | | | | 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.

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.

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.

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.

* 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.
