Hai,
I am using IBM PPC440GX board.In arch/powerpc/cpu/ppc4xx/u-boot.lds i am
changing the values of resetvector and BSS addresses but it is not changing
Presently i am changed


#if (RESET_VECTOR_ADDRESS == 0xfffffff0)
  . |= 44780000;
#endif
#endif /* CONFIG_SPL */

  __bss_start = .;
  .bss (NOLOAD)       :

Actually Below detalis i am using in MULTI. But those  are not changing in
Uboot.
MEMORY {
    Flash_memory  : ORIGIN = 0xfffBC000, LENGTH = 0x7000
    Flash_memory_start : ORIGIN = 0xFFFFF000, LENGTH = 0x0FDF
    reset_init :            ORIGIN = 0xFFFFFFF0, LENGTH = 0x0010
    ram_main  :            ORIGIN = 0x44780000, LENGTH = 1M
}

DEFAULTS {

    heap_reserve = 32k
    stack_reserve = 32K

}
SECTIONS
{
    .PPC.EMB.sdata0                    ABS : > Flash_memory
    .PPC.EMB.sbss0                            CLEAR ABS : > .
    .vectors :> Flash_memory_start
    .control                   : {*(.control)}       > Flash_memory_start
    .prefetch    : {*(.prefetch)} >  .
    .reset_vec               : {*(.reset_vec)} > reset_init
        .text               : > Flash_memory
    .vletext     : > .
    .syscall     : > .
    .secinfo     : > .
    .rodata     : > .
    .textprefetch     : {*(.textprefetch)} > .
    .sdata2     : > ram_main
    .fixaddr   : > .
    .fixtype : > .

    .sdabase              ALIGN(16) : > ram_main
    .sdata : > ram_main
    .sbss : > .
    .data : > .
    .bss   : > .
    .heap                  ALIGN(16) PAD(heap_reserve)  : > .
    .stack                 ALIGN(16) PAD(stack_reserve) : > .

     INTR_VECTOR_START = ADDR(.vectors);
}

It looks like you forgot "0x" here.
