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@12100000

rename to timer@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?
