* powerpc/mpc8xxx: Add fine timing support for DDR3York Sun2012-08-231-1/+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. Snyder2011-11-291-0/+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 Sun2011-07-111-1/+3

* mpc8xxx: DDR2/DDR3: Clean up DIMM-type switch statementsKyle Moffett2011-04-041-9/+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 supportyork2010-07-261-0/+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.

* fsl-ddr: add the DDR3 SPD infrastructureDave Liu2009-03-301-1/+12
| | | | | | | | | - support mirrored DIMMs, not support register DIMMs - test passed on P2020DS board with MT9JSF12872AY-1G1D1 - test passed on MPC8569MDS board with MT8JSF12864HY-1G1D1 Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Travis Wheatley <travis.wheatley@freescale.com>
* Add proper SPD definitions for DDR1/2/3James Yang2008-08-271-0/+292
Also adds helper functions for DDR1/2 to verify the checksum. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
