* driver/ddr/fsl: Add DDR4 support to Freescale DDR driverYork Sun2014-04-22-1/+225
| | | | | | | Mostly reusing DDR3 driver, this patch adds DDR4 SPD handling, register calculation and programming. Signed-off-by: York Sun <yorksun@freescale.com>
* powerpc: Fix CamelCase warnings in DDR related codePriyanka Jain2013-10-16-24/+24
| | | | | | | | | | | Some DDR related structures present in fsl_ddr_dimm_params.h, fsl_ddr_sdram.h, ddr_spd.h has various parameters with embedded acronyms capitalized that trigger the CamelCase warning in checkpatch.pl Convert those variable names to smallcase naming convention and modify all files which are using these structures with modified structures.

* powerpc/mpc8xxx: Add fine timing support for DDR3York Sun2012-08-23-1/+6
| | | | | | | | When the DDR3 speed goes higher, we need to utilize fine offset from SPD. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
* mpc8xxx: update module_type values from JEDEC DDR3 SPD SpecificationIra W. Snyder2011-11-29-0/+7
| | | | | | | | | | Newer JEDEC DDR3 SPD Specifications define several additional values for the DDR3 module_type field which were undefined when this code was written. Update the code to handle the newer module types. Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu> Cc: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Adding more SPD registersYork Sun2011-07-11-1/+3
| | | | | | | Adding byte 32 and 33 Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* mpc8xxx: DDR2/DDR3: Clean up DIMM-type switch statementsKyle Moffett2011-04-04-9/+19
| | | | | | | | | | | | | | | The numeric constants in the switch statements are replaced by #defines added to the common ddr_spd.h header. This dramatically improves the readability of the switch statments. In addition, a few of the longer lines were cleaned up, and the DDR2 type for an SO-RDIMM module was added to the DDR2 switch statement.

* powerpc/8xxx: Enable DDR3 RDIMM supportyork2010-07-26-0/+14
| | | | | | | | | Enabled registered DIMMs using data from SPD. RDIMMs have registers which need to be configured before using. The register configuration words are stored in SPD byte 60~116 (JEDEC standard No.21-C). Software should read those RCWs and put into DDR controller before initialization.
