mxs: spl_mem_init: Align DDR2 init with FSL bootlets source
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.
