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.

common: arm: freescale: layerscape: Move header files out of common.h

2017-06-05T18:12:59Z

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

2017-06-05T16:30:55Z

The declarations should not be in common.h. Move them to the arch-specific headers. Signed-off-by: Simon Glass [trini: Fixup thinko defined(FSL_LSCH3) -> defined(CONFIG_FSL_LSCH3)] Signed-off-by: Tom Rini

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.
