Stuck after 3.

It seems it doesn't allow write mmio.

int probe_49fl004 (struct flashchip * flash)
        volatile char * bios = flash->virt_addr;
        unsigned char  id1, id2;
        *(volatile char *) (bios + 0x5555) = 0xAA;
        *(volatile char *) (bios + 0x2AAA) = 0x55;
        *(volatile char *) (bios + 0x5555) = 0x90;
