[U-Boot] {Spam?} u-boot relocation

Hi,

I updated my u-boot-usb to continue my work on the SAM9 USB parts, but got 
stuck with the following issue :

There seems to be a new relocation scheme. I also added some stuff to make it 
detect the SDRAM, but than I get stuck.

 int dram_init(void)
{
        gd->bd->bi_dram[0].start = PHYS_SDRAM;
        gd->bd->bi_dram[0].size = PHYS_SDRAM_SIZE;
        /* dram_init must store complete ramsize in gd->ram_size */ 
        gd->ram_size = get_ram_size((volatile void *)PHYS_SDRAM, 
PHYS_SDRAM_SIZE);
        dram_init_banksize();
        return 0;
}

Booting looks like this :

U-Boot 2010.12-09749-g8da60f4-dirty (Dec 25 2010 - 18:44:18)

U-Boot code: 73F00000 -> 73F3F6F4  BSS: -> 73F51A8C
monitor len: 00051A8C
ramsize: 08000000
TLB table at: 77ff0000
Top of RAM usable for U-Boot at: 77ff0000
Reserving 326k for U-Boot at: 77f9e000
Reserving 384k for malloc() at: 77f3e000
Reserving 24 Bytes for Board Info at: 77f3dfe8
Reserving 144 Bytes for Global Data at: 77f3df58
New Stack Pointer is: 77f3df50
RAM Configuration:
Bank #0: 70000000 128 MiB
relocation Offset is: 0409e000

Here it stopsand although I have been reading the relocation readme, it 
doesn't give me any clues where to look for. 

My board has 1M NOR flash which holds u-boot. I read something in the readme 
about it, which makes me believe I need some additional things. 

Does anyone have an idea what I can do to get this to boot again ?

Best regards,
Marcel
