York Sun	5614e71b49	Driver/DDR: Moving Freescale DDR driver to a common driver ... Freescale DDR driver has been used for mpc83xx, mpc85xx, mpc86xx SoCs. The similar DDR controllers will be used for ARM-based SoCs. Signed-off-by: York Sun <yorksun@freescale.com>	2013-11-25 11:43:43 -08:00
York Sun	dea8bd627c	powerpc/85xx: Update fixed DDR3 timing table for P4080DS ... 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.

Kumar Gala	5cfbc458d4	powerpc/85xx: Remove DATARATE_*_MHZ defines in static ddr init ... 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.

York Sun	28a966715b	Adding fixed sdram setting for cornet_ds board ... 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>	2010-10-20 02:38:39 -05:00
