      LC15: Fix flakey ddr3 detection with ref_ctrl and ref_ctrl_final · babb512f
      Tony Lindgren authored
      Since commit 802bb57a ("ARM: DRA7: EMIF: Update SDRAM_REF_CTRL
      register value") we now do this in two phases.
      
      We are not currently configuring ref_ctrl and this seems to cause
      bogus memory errors early in u-boot that often happen if the board
      has been powered off for a while:
      
      SDRAM: identified size not same as expected size identified: 0
      expected: 40000000
      ...
      WARNING: DDR RAM is not working! (12000000)
      ...
      ### ERROR ### Please RESET the board ###
      
      Note that this does not solve the kernel related memory issues,
      but gets us to the point where u-boot starts reliably.
