28MiB in size, we put it to roughly 5x size into memory and the
devicetree behind it. The kernel should then unpack itself to the start
of SDRAM. Looks good and It seems barebox actually jumps to the Kernel.
Next thing to try would be enabling CONFIG_DEBUG_LL,
CONFIG_DEBUG_UNCOMPRESS and CONFIG_EARLY_PRINTK in the Kernel. Pass
"earlyprintk" as kernel option and let's see what happens then.
