* fdt: Rename the DEV_TREE_BIN Makefile flag to to EXT_DTBSimon Glass2014-06-19-2/+2
| | | | | | | This seems like a better name. This is a patch-up to the earlier commit 63b4b5b, and also removes a redundant Makefile change. Signed-off-by: Simon Glass <sjg@chromium.org>
* fdt: Add DEV_TREE_BIN option to specify a device tree binary fileSimon Glass2014-06-11-2/+14
| | | | | | | | | | | | | | 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 Signed-off-by: Simon Glass <sjg@chromium.org>
* FDT: Fix DTC repository referencesJon Loeliger2014-06-05-2/+2
| | | | | | | | | | | | | 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.

* Add minor updates to README.fdt-controlSimon Glass2013-05-14-1/+8
| | | | | | | A few things have changed since this doc was written, so update it to match the current state of things. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Add CONFIG_OF_HOSTFILE to read FDT from host fileSimon Glass2013-05-01-1/+5
| | | | | | | | | | | | 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. Signed-off-by: Simon Glass <sjg@chromium.org>
* dts/Makefile: Build the user specified dtsJagannadha Sutradharudu Teki2013-04-02-0/+8
| | | | | | | This patch provides a support to build the user specified dts. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com> Acked-by: Simon Glass <sjg@chromium.org>
* fdt: ARM: Add fdtcontroladdr to set device tree address in environmentSimon Glass2011-10-26-0/+12
| | | | | | | | | | 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. Signed-off-by: Simon Glass <sjg@chromium.org>
* fdt: Add support for embedded device tree (CONFIG_OF_EMBED)Simon Glass2011-10-26-0/+172
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. Signed-off-by: Simon Glass <sjg@chromium.org>
