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
