Hi people!

I work with based on AT91RM9200  board. (SDRAM 16Mbitx16)
When i use  "#define CONFIG_SKIP_LOWLEVEL_INIT"  and "#define
CONFIG_SKIP_RELOCATE_UBOOT" then U-BOOT does not work.

But if to change a lines  in file "/cpu/arm920t/at91rm9200/lowlevel_init.S"  :

    ldr     r0, =SMRDATA
    ldr     r1, _MTEXT_BASE
    sub     r0, r0, r1
    add     r2, r0, #32  //this number valid for me
and
    ldr     r0, =SMRDATA1
    ldr     r1, _MTEXT_BASE
    sub     r0, r0, r1
    add     r2, r0, #160  //this number valid for me

to a line

    ldr     r0, =SMRDATA
    add     r2, r0, #32  //this number valid for me
and
    ldr     r0, =SMRDATA1
    add     r2, r0, #160 //this number valid for me

works correctly

How to solve a problem?
Thank

Alexandr
