Wrong relocation with Mini2440

[luigi origa]

I'm trying to have barebox working on my mini2440. After many test,
today i got a jtag interface and after some check i found this:

- source s3c24x0_nand_boot -
2: ldr sp, =(TEXT_BASE - SZ_2M) /* Setup a temporary stack in SDRAM */
/*
 * We still run at a location we are not linked to. But lets still running
 * from the internal SRAM, this may speed up the boot
 */
push {lr}
bl nand_boot
pop {lr}
/*
 * Adjust the return address to the correct address in SDRAM
 */
ldr r1, =(TEXT_BASE - SZ_2M)
add lr, lr, r1

mov pc, lr

s3c24x0_nand_load_image(dest, size, page);

0x33c00000 is the sdram stack where the program should be copied from
nand. Unfortunately the function nand_boot copy from nand to sdram
@0x33e00000.

When s3c24x0_nand_boot try to jump in sdram, use  a wrong address
(0x33c00220 instead 0x33e00220).

I don't know if the problem is in "TEXT_BASE - SZ_2M" or "_text".
