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.

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?
