* arm: mvebu: a38x: Remove dead code ARMADA_39XPali Rohár2021-03-123-17/+0
| | | | | | | | | | | Config option ARMADA_39X is never set so remove all dead code hidden under ifdef CONFIG_ARMADA_39X blocks. Also remove useless checks for CONFIG_ARMADA_38X define as this macro is always defined for a38x code path. Signed-off-by: Pali Rohár <pali@kernel.org> Reviewed-by: Stefan Roese <sr@denx.de>
* ddr: marvell: a38x: Sync code with Marvell mv-ddr-marvell repositoryPali Rohár2021-03-1210-40/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This syncs drivers/ddr/marvell/a38x/ with the master branch of repository https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git up to the commit 7c351731d196 ("Merge pull request #29 from pali/sync-a38x-uboot"). 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 and ddr3: files=drivers/ddr/marvell/a38x/* sed 's/#if defined(CONFIG_ARMADA_38X) || defined(CONFIG_ARMADA_39X)/#ifdef TRUE/' -i $files unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_DDR4 -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 -DTRUE $files 3. Manually omit SPDX-License-Identifier changes from this patch as 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 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 is removal of dead code and some fixes with include files.

* ddr: marvell: a38x: fix comment in conditional macroMarek Behún2021-02-261-1/+1
| | | | | | | | | | The code was processed with unifdef utility to omit portions not relevant to A38x and DDR3. This removes usage of many macros, including A70X0, A80X0 and A3900.

| | | | | | | | | | | | Bump version of a38x DDR3 trianing to version 14.0.0 to reflect the version in the mv-ddr-devel branch of upstream repository https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git. There is a new version numbering system, where after 18.12.0 came 1.0.0, 2.0.0, and so on until 14.0.0. So 14.0.0 is newer than 18.12.0.

| | | | | | | | | | | | | | | | | | | commit 56db5d1464b44df10a02b99e615ebd6f6a35c428 upstream. @pali suggested this change In commit 6285efb ("mv_ddr: add support for twin-die combined memory device") was added support for twin-die combined memory device and default value for explicitly uninitialized structure members is zero, s also twin_die_combined is initialized to zero. Which means COMBINED value. As prior this commit there was no support for twin-die combined memory device, default value for twin_die_combined should be NOT_COMBINED.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-0743-87/+43
| | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | 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>
* ddr: marvell: update additional ODT settingChris Packham2018-01-191-8/+14
| | | | | | | | | | | The RD_SAMPLE_DELAY field is 5 bits so it needs to be masked with 0x1f instead of 0xf. Rather than checking the read sample delay for all DDR chip selects use the values for the chip selects that are actually configured. Finally continue searching for the max_phase value even if the current read_sample is the same as the max_read_sample.

* ddr: marvell: only assert M_ODT[0] on write for a single CSChris Packham2018-01-193-8/+13
| | | | | | | | | | | 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.

* driver/ddr: Add support for setting timing in hws_topology_mapMarek Behún2017-07-122-0/+15
| | | | | | | | | | | | | | | | | | | | | 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.
