* dtc: optionally add add __symbols__ to build-in devicetreeMichael Tretter2019-09-161-0/+16
| | | | | | | | | | | | | | | | The devicetree overlay driver requires the __symbols__ node to resolve phandles to the base devicetree. If Barebox has to apply the overlay to the live devicetree, the build-in devicetree must be built with the __symbols__ node. It is configurable, because adding __symbols__ significantly increases the size of the devicetree binary. When configuring Barebox, a developer should be able to enable or disable devicetree overlay support and as this only affects the build-in devicetree, which is linked to the image anyway, use a Kconfig item for configuring the __symbols__.

* of: add support for devicetree overlaysMichael Tretter2019-09-161-0/+9
| | | | | | | | | | | | | | | The devicetree overlay support is based on the Linux driver for device tree overlays, but many features that are not required in Barebox are left out. Unlike Linux, which applies the overlay to the live devicetree, Barebox registers a fixup for the overlay which is applied with other fixups to whatever tree is fixed. This is necessary to apply the overlay to devicetrees that are passed to Linux, which might differ from the devicetree that is currently live in Barebox.

* environment: Support env from file in a file-system via device treeTrent Piepho2016-01-081-0/+7
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | DT PCI address translation needs a special handling. This imports the corresponding translator into of/address.c but makes it selectable through Kconfig. Compared to the Linux version, we don't check for struct device_node's type which does not exist on Barebox but directly for device_type property set to "pci".

* Add configurability via devicetreeSascha Hauer2013-07-181-0/+9
| | | | | | | | | | | | | | | | | | This adds the possibility to configure the place for the environment from the devicetree and to partition devices from the devicetree. Configuration has the general form of devices with a regular compatible property. This allows to later add additional drivers or drivers with different behaviour (for example to add support for redundant environment). The configuration is all in the /chosen/barebox/ hierarchy of the devicetree. This separates the configuration from the hardware description. Also it makes it possible to store the configuration in a completely separate devicetree (or devicetree overlay). For the same reason all configuration is done using nodepathes rather than phandles.

* of: separate out "generic" memory bank addingAntony Pavlov2013-05-131-0/+5
| | | | | | | | | | | | | | | This patch separates out the "generic" memory segment registration function (of_add_memory_bank()) from of_add_memory(). The MIPS architecture has different view on memory resources than the ARM and PPC architectures so the "generic" of_add_memory_bank() is unusable for the MIPS architecture. We can add MIPS-specific of_add_memory_bank() into arch/mips code. Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | OFDEVICE decides whether or not we compile in support for probing devices from the devicetree. Let the user decide this explicitly. This makes the oftree, of_node and of_property commands independent of devicetree device support since being able to manipulate devicetrees has nothing to do with probing devices from the devicetree.
