2019-02-19drivers/ddr/fsl: Update fsl_ddr_board_options as weak functionPriyanka Jain
fsl_ddr_board_options is generally defined in board board's ddr.c, but some boards like lx2160ardb board does not need this function. Defining fsl_ddr_board_options as weak function to resolve compilation errors for such boards.

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>

2018-01-30drivers/ddr/fsl: Add calculation of register control wordsYork Sun
DDR4 RDIMM has some information in SPD to be used to calculate the control words for register chip. The rest can be found from JEDEC spec DDR4RCD02. Signed-off-by: York Sun <york.sun@nxp.com>

2017-08-16env: Rename getenv/_f() to env_get()Simon Glass
We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

2017-04-17drivers: ddr: fsl: fix unused-const-variable warningsThomas Schaefer
Depending on DDR configuration, gcc-6.x will show up unused-const- variable messages. Use __maybe_unused specifier for all dynamic_odt variable definitions to remove these warnings. Memory footprint will not increase as gcc will optimize out unused constants. Signed-off-by: Thomas Schaefer <thomas.schaefer@kontron.com> Signed-off-by: York Sun <york.sun@nxp.com>

2015-08-03drivers/ddr/fsl: Adjust bstopre valueYork Sun
By default the bstopre value has been set to 0x100, used to be 1/4 value of refint. Modern DDR has increased the refresh time. Adjust to 1/4 of refresh interval dynamically. Individual board can still override this value in board ddr file, or to use auto-precharge. Signed-off-by: York Sun <yorksun@freescale.com>
2015-04-23driver/ddr/fsl: Fix driver to support empty first slotYork Sun
CS0 was not allowed to be empty by u-boot driver in the past to simplify the driver. This may be inconvenient for some debugging. This patch lifts the restrictions. Controller interleaving still requires CS0 populated. Signed-off-by: York Sun <yorksun@freescale.com>
2015-02-24driver/ddr/fsl: Add support for multiple DDR clocksYork Sun
Controller number is passed for function calls to support individual DDR clock, depending on SoC implementation. It is backward compatible with exising platforms. Multiple clocks have been verifyed on LS2085A emulator. Signed-off-by: York Sun <yorksun@freescale.com>
2014-09-25driver/ddr/fsl: Fix tXP and tCKEYork Sun
The driver was written using old DDR3 spec which only covers low speeds. The value would be suboptimal for higher speeds. Fix both timing according to latest DDR3 spec, remove tCKE as an config option. Signed-off-by: York Sun <yorksun@freescale.com>
2014-09-25driver/ddr: Restruct driver to allow standalone memory spaceYork Sun
U-boot has been initializing DDR for the main memory. The presumption is the memory stays as a big continuous block, either linear or interleaved. This change is to support putting some DDR controllers to separated space without counting into main memory. The standalone memory controller could use different number of DIMM slots.
