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;
printf("3\n");
*(volatile char *) (bios + 0x5555) = 0xAA;
myusec_delay(10);
printf("4\n");
*(volatile char *) (bios + 0x2AAA) = 0x55;
myusec_delay(10);
printf("5\n");
*(volatile char *) (bios + 0x5555) = 0x90;
