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 Signed-off-by: Chris Packham <judge.packham@gmail.com> Reviewed-by: Stefan Roese <sr@denx.de> Tested-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Stefan Roese <sr@denx.de>
