fdt: Rename the DEV_TREE_BIN Makefile flag to to EXT_DTB

2014-06-19T15:18:56+00:00

This seems like a better name. This is a patch-up to the earlier commit
63b4b5b, and also removes a redundant Makefile change.

fdt: Add DEV_TREE_BIN option to specify a device tree binary file

2014-06-11T20:25:46+00:00

In some cases, an externally-built device tree binary is required to be
attached to U-Boot. An example is when using image signing, since in that
case the .dtb file must include the public keys.

Add a DEV_TREE_BIN option to the Makefile, and update the documentation.

Usage is something like:

	make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb

FDT: Fix DTC repository references

2014-06-05T18:44:56+00:00

The Device Tree Compiler (DTC) used to have its master
repository located on jdl.com.  While it is still there,
its official, new, shiny location is on kernel.org here:

    git://git.kernel.org/pub/scm/utils/dtc/dtc.git

Update a few references to point there instead.

config: don't define CONFIG_ARCH_DEVICE_TREE

2013-08-02T22:30:11+00:00

Now that nothing uses CONFIG_ARCH_DEVICE_TREE, stop defining it.

A few things have changed since this doc was written, so update it to
match the current state of things.

sandbox: Add CONFIG_OF_HOSTFILE to read FDT from host file

2013-05-01T15:17:21+00:00

With sandbox it is tricky to add an FDT to the image at build time (or
later) since we build an ELF file, not a plain binary, and the address
space of the whole U-Boot is not accessible in the emulated memory map
of sandbox.

Sandbox can read files directly from the host, though, so add an option
to read an FDT from a host file on start-up.

fdt: ARM: Add fdtcontroladdr to set device tree address in environment

2011-10-26T19:40:16+00:00

This adds support for a new environment variable called 'fdtcontroladdr'. If
defined, the hex address is used as the address of the control fdt for U-Boot.

Note: I have not changed CONFIG_PRAM section as I already have an
outstanding patch on that.

fdt: Add support for embedded device tree (CONFIG_OF_EMBED)

2011-10-26T19:38:59+00:00

This new option allows U-Boot to embed a binary device tree into its image
to allow run-time control of peripherals. This device tree is for U-Boot's
own use and is not necessarily the same one as is passed to the kernel.

The device tree compiler output should be placed in the $(obj)
rooted tree. Since $(OBJCOPY) insists on adding the path to the
generated symbol names, to ensure consistency it should be
invoked from the directory where the .dtb file is located and
given the input file name without the path.

This commit contains my entry for the ugliest Makefile / shell interaction
competition.
