* treewide: Add missing includesSascha Hauer2013-11-081-0/+1
| | | | | | | | A lot of files rely on include/driver.h including include/of.h (and this including include/errno.h. include the files explicitly so we can eventually get rid of including of.h from driver.h Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

This is done as preparation for more dynamic devicetrees where parts are loaded at runtime. Here we don't want to keep the list of phandles in sync.

* Implement bootloader spec support for bareboxSascha Hauer2013-10-141-0/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Bootloader Specification describes a way how kernels can be installed on devices and how they can be started by the bootloader. The bootloader spec is currently supported by (x86) gummiboot and by systemd which provides a kernel-install script. With the bootloader spec it's possible for the Operating system to install a new kernel without knowing about the bootloader and for the bootloader it's possible to discover and start Operating Systems on a media without being configured. For more details about the spec see: http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/ This patch adds barebox support for the spec. It enhances the 'boot' command so that not only boot script names can be given, but also devices containing bootloader spec entries. With this it's possible to call the 'boot' command like: 'boot sd emmc net'. It would then first look for bootloader spec entries on the (removable) sd card, then, is nothing is found, on the internal emmc and if still unsuccessful would call the 'net' bootscript. The bootloader Spec currently doesn't specify which entry should be default if multiple entries are found on a single device. Therefore barebox currently has two extensions of the spec. The $BOOT diretory can contain a file named 'default'. If present, the content of the file is treated as a filename under $BOOT/loader/entries/ which is used as default. Similarly if a file named 'once' is present, the entry is started once and the file is removed afterwards. This is useful for testing if a newly installed kernel works before making it the default. As on ARM and other Architectures a devicetree has to be specified for the kernel, the 'devicetree' property is used to specify a devicetree. Like 'kernel' and 'initrd' this also contains a pth relative to $BOOT. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
