From XBL:
0x14680000, 0x0002A000, "IMEM Base"
Is there anything in that wider address range that would interest
us? I recall Alex once dug into that when diving into IPA, but
I can not recall the conclusion..
Spec-wise, yes IPA do own these 0x146A8000 - 0x146AA000 .
But, not sure what they use it for.
The DT should not reflect the organization structure. Let's see if Alex
have any input on this.
Thanks,
Bjorn
