[PXA320] How to find I/O registers, base address of ASIX ethernet chip?

Hello

I use u-boot.

In U-BOOT:

MSC1 (address 0x4a00000c) - 0x0779
$ md.w 0x4a00000c
4a00000c: 0779 0000 0000 0000 0000 0000 0000 0000 y...............
4a00001c: 0008 0000 0000 0000 0000 0000 0000 0000 ................
4a00002c: 0000 0000 0000 0000 0000 0000 0000 0000 ................
4a00003c: 0000 0000 0000 0000 0000 0000 0000 0000 ................

CSADRCFG2 (address 0x4a000088) - 0032c809
$ md.l 0x4a000088
4a000088: 0032c809 00020000 00020000 00000000 ..2.............
4a000098: 00000000 00000000 00000000 00000000 ................
4a0000a8: 00000000 00000000 00000000 00000000 ................
4a0000b8: 00000000 00000000 00000000 00000000 ................
4a0000c8: 00000000 00000000 00000000 00000000 ................

As I think everythig is right and corresponds to a code

int board_init (void)
{
/* arch number for linux kernel */
gd->bd->bi_arch_number = MACH_TYPE_COLIBRI320;

/* adress of boot parameters */
gd->bd->bi_boot_params = 0x80000100;

/* configuration for ethernet chip */
CKENB |= CKENB_7_GPIO;
GPIO3 = 0x00001c01;
MSC1 = 0x779;
CSADRCFG2 = 0x0032C809;

return 0;
}


Thanks
