fdt: Add support for embedded device tree (CONFIG_OF_EMBED) 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>

dts: re-write dts/Makefile more simply with Kbuild Useful rules in scripts/Makefile.lib allows us to easily generate a device tree blob and wrap it in assembly code. We do not need to parse a linker script to get output format and arch. This commit deletes ./u-boot.dtb since it is a copy of dts/dt.dtb. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

dts: generate multiple device tree blobs It is convenient to have all device trees on the same SoC compiled.

dts/Makefile: unify cpp/dtc include paths *.dts may use #include (via cpp) or /include/ (via dtc; assuming a newer dtc). The choice is up to the creator of the DT. Create a common variable DTC_INCDIRS that lists the paths searched by include statements, and update cpp and dtc invocation to use them. For cpp, also specify -nostdinc to ensure the same set of paths is available to both type of include statement. For dtc, create a new DTC_FLAGS variable to hold all the flags passed to dtc.
