command: Remove the cmd_tbl_t typedef

2020-05-18T22:36:55+00:00

We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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

ddr: fsl: Merge macro CONFIG_NUM_DDR_CONTROLLERS and CONFIG_SYS_NUM_DDR_CTRLS

2017-01-05T00:40:52+00:00

These two macros are used for the same thing, the total number of DDR controllers for a given SoC. Use SYS_NUM_DDR_CTRLS in Kconfig and merge existing usage. Signed-off-by: York Sun

fsl/ddr: Add erratum_a009942_check_cpo and clean related erratum

2016-12-05T16:31:45+00:00

- add additional function erratum_a009942_check_cpo to check if the board needs tuning CPO calibration for optimal setting. - move ERRATUM_A009942(with revision to check cpo_sample option) from fsl_ddr_gen4.c to ctrl_regs.c for reuse on all DDR4/DDR3 parts. - move ERRATUM_A008378 from fsl_ddr_gen4.c to ctrl_regs.c - remove obsolete ERRATUM_A004934 which is replaced with ERRATUM_A009942.

Add more SPDX-License-Identifier tags

2016-01-19T13:31:21+00:00

In a number of places we had wordings of the GPL (or LGPL in a few cases) license text that were split in such a way that it wasn't caught previously. Convert all of these to the correct SPDX-License-Identifier tag. Signed-off-by: Tom Rini

drivers/ddr/fsl: Enable detection of one DDR controller operation for LSCH3

2015-11-30T17:11:11+00:00

Freescale LSCH3 platforms use two DDR controlers interleaving mode out of reset. It can be configured to disable one controller. To support this operation, the driver needs to detect and skip the disabled controller. Signed-off-by: York Sun

drivers/ddr/fsl: Adjust bstopre value

2015-08-03T19:06:38+00:00

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
