Another way to solve this problem is to use objcopy to convert the
data file into an ELF format file and then just link it in.  For
example:

  objcopy -I binary -O elf32-little-arm data_file new_object.o

You may get an error message "Warning: Output file cannot represent
architecture UNKNOWN!" in which case add a -B option like this:

  objcopy -I binary -O elf32-little-arm -B arm data_file new_object.o

This will create an object file with the data in a .data section.  If
this is unsuitable you can then use the linker and a small little
script to rename the section to something else, as in:

  ld -T convert.ls new_object.o -o resectioned_object.o

and the linker script looks like:

  SECTIONS
  {
	.new_section_name : { *(.data) }
  }

Cheers
