Space. But you already knew that. ;-)

Use the latest version of "dtc" with the -S <space> parameter and you will also want to add reserve map entries with the -R <n> parameter or bootm will fail when it tries to add the initrd memory region to the reserved map.

This following makefile works well for me (WARNING: it is whitespace damaged because I cut & pasted it - replace the spaces with tabs or make will barf).

# # Make device tree blobs #

src = $(wildcard *.dts) out = $(src:.dts=.dtb) asm = $(src:.dts=.dtb)

QUIET = #-q RESERVE = -R 4 SIZE = -S 0x3000

all: $(out)

%.dtb : %.dts dtc $(QUIET) $(RESERVE) $(SIZE) -b 0 -O dtb -f -o $@ $^

%.asm : %.dts dtc $(QUIET) $(RESERVE) $(SIZE) -b 0 -O asm -f -o $@ $^
