= Encryption used in SPI Flash =

SPI Flash dumps are encrypted with the same key and iv and AES CTR, so it's possible to retrieve delta from xoring two different drive dumps.
NOR Flash dumps are encrypted with the same key and iv and AES CTR, so it's possible to retrieve delta from xoring two different drive dumps.
The only exception is in offset 0x10000 with size 0xC0000, which is part of Bluray Drive "Firmware" (i think it's a patch of sorts but it's impossible to confirm by myself), which probably uses CBC or some other encryption algorithm.
