      mxs: spl_mem_init: Align DDR2 init with FSL bootlets source · b33426ca

      Currently the following kernel hang happens when loading a 2.6.35 kernel from
      Freeescale on a mx28evk board:
      
      RPC: Registered tcp transport module.
      RPC: Registered tcp NFSv4.1 backchannel transport module.
      Bus freq driver module loaded
      IMX usb wakeup probe
      usb h1 wakeup device is registered
      mxs_cpu_init: cpufreq init finished
      ...
      
      Loading the same kernel using the bootlets from the imx-bootlets-src-10.12.01
      package, the hang does not occur.
      
      Comparing the DDR2 initialization from the bootlets code against the U-boot
      one, we can notice some mismatches, and after applying the same initialization
      into U-boot the 2.6.35 kernel can boot normally.
      
      Also tested with 'mtest' command, which runs succesfully.
