Chris Packham ebb1a59325 ARM: mvebu: a38x: sync ddr training code with mv_ddr-armada-18.09.02
This syncs drivers/ddr/marvell/a38x/ with the mv_ddr-armada-18.09 branch
of https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git.
Specifically this syncs with commit 99d772547314 ("Bump mv_ddr to
release armada-18.09.2").

The complete log of changes is best obtained from the mv-ddr-marvell.git
repository but some relevant highlights are:

  ddr3: add missing txsdll parameter
  ddr3: fix tfaw timimg parameter
  ddr3: fix trrd timimg parameter
  merge ddr3 topology header file with mv_ddr_topology one
  mv_ddr: a38x: fix zero memory size scrubbing issue

The upstream code is incorporated omitting the portions not relevant to
Armada-38x and DDR3. After that a semi-automated step is used to drop
unused features with unifdef

    find drivers/ddr/marvell/a38x/ -name '*.[ch]' | \
        xargs unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_DDR4 \
                 -UCONFIG_APN806 -UCONFIG_MC_STATIC \
                 -UCONFIG_MC_STATIC_PRINT -UCONFIG_PHY_STATIC \
                 -UCONFIG_64BIT -UCONFIG_A3700 -UA3900 -UA80X0 \
                 -UA70X0
