i change my code and made use of mips-cm. unit boots fine now and indeed
C0_CMGCRBase holds the valid address. I will look into updating the gic
code to use the generic driver once i cleaned up the remainig mt7621
patches.
i had to apply a hack to mips-cm.c to disable the "disable CM regions"
code, this deadlocked the mt7621. i will send a separate regarding this
in a sec.
