tools/mkimage: Make the path to the dtc binary that mkimage calls configurable

2017-09-24T11:33:03Z

In some cases, such as FreeBSD, the path to an alternative dtc needs to be used. Rather than override the one given in the Makefile on the command line, make this part of the build configuration. Signed-off-by: Tom Rini

dtc: Switch to building and using our own dtc unless provided

2017-09-24T11:32:24Z

This makes us act like the Linux Kernel does and allow for dtc to be provided externally but otherwise we use the version of dtc that is included in the sources. This in turn means that we can drop the checkdtc logic. We select DTC in the cases where we will need the dtc tool provided. Signed-off-by: Tom Rini

spl: dm: Kconfig: split OF_CONTROL and OF_PLATDATA between SPL and TPL

2017-08-13T15:12:20Z

For the RK3368, we want to use OF_PLATDATA in TPL, but full OF_CONTROL in SPL: this requires the introduction of a new family of configuration options to decouple SPL_OF_CONTROL and SPL_OF_PLATDATA from TPL. Consequently, Makefile.spl needs to be adjusted to test for these configuration items through the $(SPL_TPL_) macro instead of hard-coding the SPL variant.

dts: Allow OF_LIST to depend on FIT_EMBED

2017-07-10T18:25:53Z

OF_LIST will be useable by SPL and U-boot. Therefore, update its dependency to allow it to be enable by either SPL or U-boot specific config option. Signed-off-by: Franklin S Cooper Jr Reviewed-by: Tom Rini Reviewed-by: Lokesh Vutla Acked-by: Andrew F. Davis

dm: core: Add livetree definitions

2017-06-01T13:03:06Z

Add a Kconfig option to enable a live device tree, built at run time from the flat tree. Also add structure definitions and a root node. Signed-off-by: Simon Glass

Allow boards to initialize the DT at runtime.

2017-05-10T00:35:06Z

In some boards like the Raspberry Pi the initial bootloader will pass a DT to the kernel. When using U-Boot as such kernel, the board code in U-Boot should be able to provide U-Boot with this, already assembled device tree blob. This patch introduces a new config option CONFIG_OF_BOARD to use instead of CONFIG_OF_EMBED or CONFIG_OF_SEPARATE which will initialize the DT from a board-specific funtion instead of bundling one with U-Boot or as a separated file. This allows boards like the Raspberry Pi to reuse the device tree passed from the bootcode.bin and start.elf firmware files, including the run-time selected device tree overlays.

dm: avoid dropping pin control DT properties in case of SPL_PINCTRL

2017-04-05T02:15:10Z

This patch replaces SPL_PINCTRL_FULL with SPL_PINCNTRL. It is to avoid removal of pin control properties in case of SPL_PINCTRL. No impact in case of SPL_PINCTRL_FULL as it depends on SPL_PINCTRL. Signed-off-by: Vikas Manocha Reviewed-by: Simon Glass

dm: Add callback to modify the device tree

2017-03-23T14:46:23Z

Certain boards come in different variations by way of utilizing daughter boards, for example. These boards might contain additional chips, which are added to the main board's busses, e.g. I2C. The device tree support for such boards would either, quite naturally, employ the overlay mechanism to add such chips to the tree, or would use one large default device tree, and delete the devices that are actually not present. Regardless of approach, even on the U-Boot level, a modification of the device tree is a prerequisite to have such modular families of boards supported properly. Therefore, we add an option to make the U-Boot device tree (the actual copy later used by the driver model) writeable, and add a callback method that allows boards to modify the device tree at an early stage, at which, hopefully, also the application of device tree overlays will be possible.
