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>
