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

2018-05-07T13:34:12Z

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

drivers/ddr/fsl: Add calculation of register control words

2018-01-30T17:14:07Z

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

drivers/ddr/fsl: Add 3DS RDIMM support

2018-01-30T17:14:07Z

On top of RDIMM support, add new register calculation to support 3DS RDIMMs. Only symmetrical 3DS is supported at this time. Signed-off-by: York Sun

drivers/ddr/fsl: Fix DDR4 RDIMM support

2018-01-30T17:14:06Z

For DDR4, command/address delay in mode registers and parity latency in timing config register are only needed for UDIMMs, but not RDIMMs. Add additional register rcw_3 for DDR4 RDIMM. Fix mirrored bit for dual rank RDIMMs. Set sdram_cfg_3[DIS_MRS_PAR] for RDIMMs. Fix calculation of timing config registers. Use hexadecimal format for printing RCW (register control word) registers.

We should not have an arch-specific header file in common.h. Adjust the board files a little so it is not needed, and drop it. Signed-off-by: Simon Glass

ddr: fsl: Merge macro CONFIG_NUM_DDR_CONTROLLERS and CONFIG_SYS_NUM_DDR_CTRLS

2017-01-05T00:40:52Z

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

2016-12-05T16:31:45Z

- 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.
