    drm/i915: Update gen12 multicast register ranges · 3bcacad3
    Matt Roper authored
    The updated bspec forcewake table also provides us with new multicast
    ranges that should be reflected in our workaround code.
    
    Note that there are different types of multicast registers with
    different styles of replication and different steering registers.  The
    i915 MCR range lists we're updating here are only used to ensure we can
    verify workarounds properly (i.e., if we can't steer register reads we
    don't want to verify workarounds where an unsteered read might hit a
    fused-off instance of the unit).  Because of this, we don't need to
    include any of the multicast ranges where all instances of the register
    will always present and fusing doesn't play a role.  Specifically, that
    means that we are not including the MCR ranges designated as "SQIDI" in
    the bspec.
