Poonam Aggrwal e1d8ed2c08 Changes in uboot DDR configuration for MPC8313eRDB 
These changes were identified by HighSmith Bill ,Mazzyar and Joseph for
DDR configuration in u-boot code. Some are related to performance, some
affect stability and some correct few basic errors in the current
configuration.

The changes have been tested and found to give better memory latency
figures on MPC8313eRDB.LMBench figures prove it.

The changes are:

- CS0_CONFIG[ AP_n_EN] is changed from 1 to 0
  (this may improve performance for application with many read
  or write to open pages).
- CS0_CONFIG[ODT_WR_CFG] is currently changed from 100 to
  001 (activating all the CS when only one is used may cause
  unwanted noise on the system)

- TIMING_CFG_1[ACTTOPRE] is changed from 9clks to 8clks (based on
  Tras=45ns)
- TIMING_CFG_1[REFREC] changed from 21 clks to 18clks.

- TIMING_CFG_2[AL] value changed from 0 setting to 1 clk to
  comply with the 3 ODT clk requirements)
- TIMING_CFG_2[CPO] was set to a reserved value, changed to RL+3/4.
- TIMING_CFG_2[FOUR_ACT] is changed from 10 clks to 6clks.

- DDR_SDRAM_MODE[AL]changed from 0 to 1.
- DDR_SDRAM_MODE[WRREC] changed from 1 clk to 3 clks.

- DDR_SDRAM_INTERVAL[REFINT] is changed from 0x0320 to 0x0510.
- DDR_SDRAM_INTERVAL[BSTOPRE] is changed from 0x64 to 0x0500.

The patch is based of git://www.denx.de/git/u-boot-mpc83xx.git
