d89a976c13 powerpc/corenet_ds: revise platform dependent parameters
This patch revised clk_adjust and wrlvl_start timings for corenet_ds, based
on testing on Virtium VL33B5163F-K9S and Kingston KVR1333D3Q8R9S/4G.

59a4089f82 corenet_ds: pick the middle value for all tested timing parameters
For DDR3 controller, the clk_adjust and wrlvl_start are platform-dependent.
The best values should be picked up from the middle of all working
combinations. This patch updates the table with confirmed values tested on
Hynix dual-rank UDIMMs (HMT125U7BFR8C-H9) at 1300MT/s, 1200MT/s, 1000MT/s,
900MT/s, 800MT/s and Kingston quad-rank RDIMMs (KVR1333D3Q8R9S/4G) at 1300MT/s,
1200MT/s, 1000MT/s.

3dbd5d7d7e powerpc/8xxx: Move fsl_is_spd() into generic 8xxx ddr code
Move the parsing of hwconfig to determine if to use spd into common code
so we can share it across all boards instead of duplicating it
everywhere.

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

90870d9846 powerpc/8xxx: Fix quad-rank DIMMs support on corenet_ds board.
The board specific parameters associated with quad rank dimms where
missing.  This fixes it so the board will function if quad rank dimms
are placed in it.
