    This patch simplifies flash_toggle() (AMD commandset), which is used to
    detect if a FLASH device is still busy with erase/program operations. On
    800MHz Canyonlands/Glacier boards (460EX/GT) the current implementation
    did not detect the busy state reliably, resulting in non erased sectors
    etc. This patch now simplifies this function by "just" comparing the
    complete data-word instead of ANDing it with the command-word (0x40)
    before the compatison. It is done the same way in the Linux implementation
    chip_ready() in cfi_cmdset_0002.c.
