* powerpc/85xx: Update fixed DDR3 timing table for P4080DSYork Sun2011-04-041-8/+8
| | | | | | | | | Most of time U-boot doesn't get an exact clock number. For example, clock 900MHz may be detected as 899.99MHz. 800MHz could be 799.99MHz. Update the table to align the desired clocks in the middle. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/85xx: Remove DATARATE_*_MHZ defines in static ddr initKumar Gala2011-04-041-15/+9
| | | | | | | | | | Rather than having #defines DATARATE_*_MHZ, lets just match what we do on the SPD code and convert the DDR frequency into MHZ and just compare with a constant. Based on patch from Poonam Aggrwal. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Adding fixed sdram setting for cornet_ds boardYork Sun2010-10-201-0/+356
800, 900, 1000, 1200MT/s data rate parameters are added for fixed sdram setting. SPD based parameters and fixed parameters can be toggled by hwconfig. To use fixed parameters, hwconfig=fsl_ddr:sdram=fixed To use SPD parameters, hwconfig=fsl_ddr:ctlr_intlv=cacheline,bank_intlv=cs0_cs1 Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
