-In commit 3fc92a215b69 ("ddr: marvell: a38x: fix SPLIT_OUT_MIX state
-decision") I ported a cleaned up and changed version of patch
-  mv_ddr: a380: fix SPLIT_OUT_MIX state decision
-
-In the port we removed checking for BYTE_HOMOGENEOUS_SPLIT_OUT bit,
-because:
-- the fix seemed to work without it
-- the bit was checked for only at one place out of two, while the second
-  bit, BYTE_SPLIT_OUT_MIX, was checked for in both cases
-- without the removal it didn't work on Allied Telesis' x530 board
-
-We recently had a chance to test on more boards, and it seems that the
-change needs to be opposite: instead of removing the check for
-BYTE_HOMOGENEOUS_SPLIT_OUT from the first if() statement, the check
-needs to be added also to the second one - it needs to be at both
-places.
-
-With this change all the Turris Omnia boards I have had available to
-test seem to work, I didn't encounter not even one failed DDR training.
-
-As last time, I am noting that I do not understand what this code is
-actually doing, I haven't studied the DDR training algorithm and
-I suspect that no one will be able to explain it to U-Boot contributors,
-so we are left with this blind poking in the code with testing whether
-it works on several boards and hoping it doesn't break anything for
-anyone :-(.
