Most of the arguments should be dropped and replaced with the respective
DT properties in this file:

mem:		/memory (you have that already, but the size seems wrong)
console:	/chosen/stdout-path
early_printk:	just drop this, maybe use "earlycon")
root:		this one is fine
rootfstype:	should not be needed
mtdparts:	use nodes below the MTD device

Move this into the .dts file.

rename to serial at 12100000

rename to timer at 12001000

Is this one identical to the one in hip04?

If not, pick a new unique compatible string

what is a "crg"? Is there a standard name for these?
