| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of_tree_for_each_node_from() is supposed to iterate over all DT nodes after the one pointed by the from parameter, but with the current of_next_node() implementation we cannot access the root node. Patch of_next_node() to point to root_node when from is NULL. Doing that also simplifies users of of_tree_for_each_node_from() which were duplicating the logic to point to the root_node when from is NULL.

| * | of: preserve /memreserve/ entriesSascha Hauer2016-04-251-6/+100
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Some dts files for the Kernel specify a reserved memory area using the /memreserve/ dtc directive. These entries get lost during unflattening/flattening the device tree and are never passed to the Kernel. This patch fixes this behaviour. This is done by copying the entries into a /memreserve node in the unflattened tree and moving them back during flattening the tree. The entries added by barebox dynamically are appended to the static entries from the original dtb. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* / string: Fix (v)asprintf prototypesSascha Hauer2016-04-154-4/+5
|/ | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

* of_path: Drop possible further extensions of device-path propertySascha Hauer2016-01-081-95/+28
| | | | | | | | | | Originally it was intended to further extend the multi string property device-path further with more elements, like for example a filename. It turned out though that this is too complex and instead of further extending the property we should instead create additional properties, so this mechanism is removed with this patch to make the code simpler.

* environment: Support env from file in a file-system via device treeTrent Piepho2016-01-082-2/+52
| | | | | | | | | | | | | | | Current barebox,environment node only allows specifying a raw device or partition to load an environment from. Some boards, like OMAP and SoCFPGA, instead want to use a file located in a FAT filesystem. Extend the device tree bindings with a new property 'file-path' that will trigger this behavior. This allows any board using this driver to get the env from a file or from a raw device, instead of each machine type being either raw device only or file only.

* of_path: Fix bug with partitions, simply codeTrent Piepho2016-01-081-18/+29
| | | | | | | | | | | | | | | | | | | | | | In commit 75b682795eafb2385556a9642f09e0af96a1264a using a path that has a partition description broke. Fix this and simpfy the code some. There is no need to loop over each string in the path property: it's defined to have at most one parition description, no extant dts has more than one, and how it would handle more than one didn't make sense anyway. Once not looping, __of_find_path() just needs the partition description text, not both the original node and property name to look it up from. When using a partition description, don't lookup the cdev of the node just to replace it with the partition's cdev.
