Instead of setting up VDDMEM in one swipe, let it rise slowly the same way as VDDD and VDDA in spl_power_init.c and then only clear ILIMIT before memory gets inited. This makes sure the VDDMEM rises sanely, not jumps up and down as it did till now. The VDDMEM prior to this change did this: 2V0____ .--------2V5 | `--' 0V____| The VDDMEM now does this: 2V0_____,-----------2V5 / 0V__| Moreover, VDDIO on MX23 uses 25mV steps while MX28 uses 50mV steps, fix this difference too.

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.
