* driver/ddr/fsl: Add DDR4 support to Freescale DDR driverYork Sun2014-04-221-1/+44
| | | | | | | Mostly reusing DDR3 driver, this patch adds DDR4 SPD handling, register calculation and programming. Signed-off-by: York Sun <yorksun@freescale.com>
* mpc8xxx: DDR2/DDR3: Clean up DIMM-type switch statementsKyle Moffett2011-04-041-1/+1
| | | | | | | | | | | | | | | 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.

* Enabled support for Rev 1.3 SPD for DDR2 DIMMsYork Sun2010-05-121-1/+5
| | | | | | | | | | | | | | SPD has minor change from Rev 1.2 to 1.3. This patch enables Rev 1.3. The difference has ben examined and the code is compatible. Speed bins is not verified on hardware for CL7 at this moment. This patch also enables SPD Rev 1.x where x is up to "F". According to SPD spec, the lower nibble is optionally used to determine which additinal bytes or attribute bits have been defined. Software can safely use defaults. However, the upper nibble should always be checked. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
