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
