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>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-01-30drivers/ddr/fsl: Modify binding registers to save time on data initYork Sun
DDR controllers always use binding register to determine the memory space to perform data initialization. In case of controller interleaving, the space is doubled, resulting twice long wait. It wasn't too bad until the memory capacity increases. To reduce the wait time, reduce the binding space to half and restore it after data initialization. Three-way interleaving is no longer used and is removed. Signed-off-by: York Sun <york.sun@nxp.com>

2018-01-30drivers/ddr/fsl: Fix DDR4 RDIMM supportYork Sun

2018-01-19ddr: marvell: update additional ODT settingChris Packham
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.

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 Behún
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.
