2018-12-08ARM: mvebu: a38x: sync ddr training code with mv_ddr-armada-18.09.02Chris Packham
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>
2018-05-14ARM: mvebu: a38x: restore support for setting timingChris Packham
This restores support for configuring the timing mode based on the ddr_topology. This was originally implemented in commit 90bcc3d38d2b ("driver/ddr: Add support for setting timing in hws_topology_map") but was removed as part of the upstream sync.

2018-05-14ARM: mvebu: a38x: sync ddr training code with upstreamChris Packham
This syncs drivers/ddr/marvell/a38x/ with the mv_ddr-armada-17.10 branch of https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git. The upstream code is incorporated omitting the ddr4 and apn806 and folding the nested a38x directory up one level. 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 INTER_REGS_BASE is updated to be defined as SOC_REGS_PHY_BASE. Some now empty files are removed and the ternary license is replaced with a SPDX GPL-2.0+ identifier. Signed-off-by: Chris Packham <judge.packham@gmail.com> Signed-off-by: Stefan Roese <sr@denx.de>
2018-05-14ARM: mvebu: a38x: remove some unused codeChris Packham
No in-tree code defines SUPPORT_STATIC_DUNIT_CONFIG or STATIC_ALGO_SUPPORT. Remove ddr3_a38x_mc_static.h and use unifdef to remove unused sections in the rest of the ddr/marvell/a38x code. Signed-off-by: Chris Packham <judge.packham@gmail.com> Signed-off-by: Stefan Roese <sr@denx.de>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-01-19ddr: marvell: update ddr controller init and freqChris Packham
Update the calculation for tWR and tPD. This improves the DDR refresh interval and brings the initialization into line with the binary blobs currently being supplied by Marvell. Signed-off-by: Chris Packham <judge.packham@gmail.com> Signed-off-by: Stefan Roese <sr@denx.de>

2018-01-19ddr: marvell: only assert M_ODT[0] on write for a single CSChris Packham
When using only a single DDR chip select only assert M_ODT[0] on write. Do not assert it on read and do not assert M_ODT[1] at all. Also set tODT_OFF_WR to 0x9 which contradicts the recommendation from the functional spec but is what Marvell's binary training blob does and seems to give better results when ODT is active during writes.

2017-07-12driver/ddr: Add support for setting timing in hws_topology_mapMarek BehĂșn
The DDR3 training code for Marvell A38X currently computes 1t timing when given board topology map of the Turris Omnia, but Omnia needs 2t. This patch adds support for enforcing the 2t timing in struct hws_topology_map, through a new enum hws_timing, which can assume following values: HWS_TIM_DEFAULT - default behaviour, compute whether to enable 2t from the number of CSs HWS_TIM_1T - enforce 1t HWS_TIM_2T - enforce 2t This patch also sets all the board topology maps (db-88f6820-amc, db-88f6820-gp, controlcenterdc and clearfog) to have timing set to HWS_TIM_DEFAULT.

2015-07-23arm: mvebu: Add Armada 38x DDR3 training code from Marvell bin_hdrStefan Roese
This patch adds the DDR3 setup and training code taken from the Marvell U-Boot repository. This code used to be included as a binary (bin_hdr) into the Armada A38x boot image. Not linked with the main U-Boot. With this code addition and the serdes/PHY setup code, the Armada A38x support in mainline U-Boot is finally self-contained. So the complete image for booting can be built from mainline U-Boot. Without any additional external inclusion. Note: This code has undergone many hours (days!) of coding-style cleanup and refactoring. It still is not checkpatch clean though, I'm afraid. As the factoring of the code has so many levels of indentation that many lines are longer than 80 chars. Signed-off-by: Stefan Roese <sr@denx.de>
