Location seed for QSPI Encryption

Question

Hello, 
 
 I have been working on the QSPI DMA encryption. As QSPI DMA encryption enabled, I noticed that QSPI cipher may use the flash location information to encrypt/decrypt. 
 Can you please confirm this one? If so, was it implemented at the SoC design or driver level? 
 
 Regards,

Hello again, 
 It is done by the hardware. You can find out about this in the product specification . 
 The stream cipher uses an AES 128 encryption operation to form the keystream from key, nonce, and external memory address.
