ddr: marvell: a38x: Add support for DDR4 from Marvell mv-ddr-marvell repository This syncs drivers/ddr/marvell/a38x/ with the master branch of repository https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git up to the commit "mv_ddr: a3700: Use the right size for memset to not overflow" d5acc10c287e40cc2feeb28710b92e45c93c702c This patch was created by following steps: 1. Replace all a38x files in U-Boot tree by files from upstream github Marvell mv-ddr-marvell repository. 2. Run following command to omit portions not relevant for a38x, ddr3, and ddr4: files=drivers/ddr/marvell/a38x/* unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_APN806 \ -UCONFIG_MC_STATIC -UCONFIG_MC_STATIC_PRINT -UCONFIG_PHY_STATIC \ -UCONFIG_PHY_STATIC_PRINT -UCONFIG_CUSTOMER_BOARD_SUPPORT \ -UCONFIG_A3700 -UA3900 -UA80X0 -UA70X0 -DCONFIG_ARMADA_38X -UCONFIG_ARMADA_39X \ -UCONFIG_64BIT $files 3. Manually change license to SPDX-License-Identifier (upstream license in upstream github repository contains long license texts and U-Boot is using just SPDX-License-Identifier. After applying this patch, a38x, ddr3, and ddr4 code in upstream Marvell github repository and in U-Boot would be fully identical. So in future applying above steps could be used to sync code again. The only change in this patch are: 1. Some fixes with include files. 2. Some function return and basic type defines changes in mv_ddr_plat.c (to correct Marvell bug). 3. Remove of dead code in newly copied files (as a result of the filter script stripping out everything other than a38x, dd3, and ddr4).
