MR: 14884
Type: Defect Fix
Disposition: needs submitting to linuxmips-embedded mailing list
Signed-off-by: Aleskey Makarov <makarov@ru.mvista.com>
Description:
    The address of IDE control register on this platform
    is not standard. Also, an unnecessary check for pci
    vendor/device/class was removed and
    an unnamed constant assignment was fixed.
