Hi all,

I am solving one merging issue and I would appreciate if someone can help me
with one problem I have.

We have in vmlinux.lds.S specify two memory regions because we use main memory
and bram memory which is faster.

MEMORY {
	ERAM	: ORIGIN = CONFIG_XILINX_ERAM_START,
		  LENGTH = CONFIG_XILINX_ERAM_SIZE
#if defined(CONFIG_XILINX_LMB_START) && defined(CONFIG_USE_BRAM)
	LMB	: ORIGIN = CONFIG_XILINX_LMB_START,
		  LENGTH = CONFIG_XILINX_LMB_SIZE
#endif
}

And then we have special section for it which is copied to proper place in
startup sequence.

       .bram : {
		/* Skip past interrupt, exception and debug vectors.  If you
		   change this, also change the 0x40 (word) offset in
		   kernel/setup.c:pingpong_bram()  */
               . = 0x100;
               _bram_load_start = . ;
               *(.bram*)               /* Everything */
               *(.bram.text)
               *(.bram.data)
               _bram_load_end = . ;
       } > LMB AT > ERAM

This concept work well but I would like to remove all reference which pointed to
memory regions and of course regions because I would like to use generic macros
which is in asm-generic/vmlinux.lds.h (especially RODATA).

I found that is possible to add memory location after name of section but this
seems work only without included data.
.name mem_lock {

}

When the data is there objcopy announced that section is too big for creating
linux.bin file. :-(

Is there any way how is possible to do it?

Thanks for any hit,
Best regards,
Michal Simek
