Yeah, workarounds like this should be as targeted as possible. If we knew the
specific chips/boards on which U-Boot has this problem, then limiting it to
those would have been even better (e.g. fix up the device tree from the
platform code), but at this point containing the damage to PPC seems like the
most reasonable approach. It's not relevant to this specific patch, but it is
relevant to a patchset expanding the set of platforms on which this code
builds.
