Re: [U-Boot] [PATCH v3 2/6] 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.

Couldn't that just be:

$(CPP) -P $(DTS_CPPFLAGS) $< >$@.tmp

• $(DTC) -R 4 -p 0x1000 -O dtb -o ${DT_BIN} $@.tmp
• rm $@.tmp
