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

2017-08-13T15:12:20+00:00

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

2017-07-10T18:25:53+00:00

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.

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.

Allow boards to initialize the DT at runtime.

2017-05-10T00:35:06+00:00

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

2017-04-05T02:15:10+00:00

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.

dm: Add callback to modify the device tree

2017-03-23T14:46:23+00:00

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.

spl: Setup default value for OF_LIST

2016-05-23T15:50:21+00:00

OF_LIST can't remain empty that's why setup it up to default DTB.

If it is empty u-boot.img is created without FDT partition:
For example:
  ./tools/mkimage -f auto -A arm -T firmware -C none -O u-boot -a
0x8000000 -e 0 -n "U-Boot 2016.05-rc3 ..." -E -b  -d u-boot-nodtb.bin u-boot.img
Can't set 'timestamp' property for '' node (FDT_ERR_NOSPACE)
FIT description: Firmware image with one or more FDT blobs
Created:         Wed May  4 15:02:52 2016

spl: Add a way to specify a list of device trees to include

2016-03-14T23:18:31+00:00

When building a FIT, more than one device tree can be included. The board
can select (at run-time) the one that it wants.

Add a Kconfig option to allow the list of devices trees (supported by the
board) to be specified.

When using SPL_LOAD_FIT, build u-boot.img in FIT format instead of the
legacy image format. Include all the listed device tree files in this FIT.
