Generate "custom" bss section that doen't occupy space in ELF

[<filter002 at desinformation dot de>]

I generated a custom bss section:


volatile Byte Fieldbuffer[Fieldbuffersize] __attribute__ ((aligned(4)))
__attribute__ ((section(".bss_uc")));


And in the linker script:

  /* uncached bss section */
  .bss_uc (NOLOAD) :
  {
    *(.bss_uc .bss_uc.*)
  } >dram_uc

The gernerated datastructures in bss_uc should not be statically initialized
at any place.

But I get a very big ELF file (luckily not the HEX file out of objcopy),
which contains data for this 'bss_uc' section.

(NOLOAD) didn't help.

How could I get my bss_uc the same way as the predefined bss so that it's
data is not placed in the ELF ?
