2022-12-05global: Move remaining CONFIG_SYS_SDRAM_* to CFG_SYS_SDRAM_*Tom Rini1-1/+1
The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>

2018-01-30drivers/ddr/fsl: Modify binding registers to save time on data initYork Sun1-11/+49
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>

DDR controller 5.2.1 has this erratum A008511 partially fixed. The workaround needs to be adjusted to take advantage of Vref training. This patch enables the training and force output enable to be off. Erratum A009803 requires the controller to be idel before enabling address parity. It was combined with workaround for A008511. With new A008511 flow, this flow needs to be changed to enabling data init (D_INIT) after the address parity is enabled.
