Info from Andrew Pinski:

Please file a bug report but I still see it on the mainline ().
Also Here is a workaround:
void flash_wait_ready(volatile unsigned *vaddr)
{
        while(1)
        {
                unsigned temp = *vaddr;
                if (temp != *vaddr)
                        break;
        }
}

Thanks,
Andrew Pinski
