-This patch is a partial backport of commit ef01c6c36bb8 ("ARM: mvebu:
-remove Armada 375 Z1 workaround for I/O coherency"). This commit was
-merged in v3.19, so kernel versions later than v3.19 are not affected
-by the problem that this commit fixes.
-
-It does not make a lot of sense to backport this commit entirely,
-since it is mainly removing some no longer useful code. However, this
-commit is also making sure that the bus_register_notifier that
-register the custom DMA operations that should be used for HW I/O
-coherency does not get registered when said HW I/O coherency is not
-enabled.
-
-This is particularly critical since we have decided to disable HW I/O
-coherency completely in all kernels < 4.0, to be on the safe side,
-while experimenting a new implementation of the HW I/O coherency in >=
-4.0.
-
-Without this commit, kernels earlier than 3.18 have the custom DMA
-operations normally used for HW I/O coherency registered (they don't
-do cache maintenance operations), while HW I/O coherency is
-disabled. It essentially causes every DMA transfer to transfer
-garbage.
-
-The issue fixed by this commit was introduced by 5ab5afd8ba83 ("ARM:
-mvebu: implement Armada 375 coherency workaround"), but it was not
-visible until now since it didn't cause any problem when HW I/O
-coherency is enabled.
