I have a problem.. help..

[Woo-Seung Yeo <wsyeo at dmc dot htc dot hanwha dot co dot kr>]

  Hi.
  I can't find where to post this mail.
  If I have wrong, sorry. but please help me.
  I am novice in using GNU tools.
  And I have a linkage problem.
  As I read at Ld info page, I have defined LMA using
  ld script command below. I checked final elf
  object using "objdump -h". The result is that VMA
  is equal to LMA. I converted final elf object file
  to s-record format using "objcopy -O srec final.o final.hex"
  In that final.hex, s-record address is started from 0x00010000.
  After a block started from 0x00010000, a block started from
  0xfff00000 existed. In map file, I can see the message that
  load address of .data output section is 0xfff13600".

  And I have ld warning messages below. What is the meaning..
      "powerpc-linux-ld: warning: no memory region specified for section
`.data'"
      "powerpc-linux-ld: bug860.o: warning: allocated section `.text'
not in segment"

  Here is ld command.
=======================
powerpc-linux-ld -T rom.ld -Map bug860.map -o bug860.o \
   --start-group <object files...> ./stubs/libstub.a -lc --end-group


  Here is output of objdump.
