[PATCH 0/4] K3: Add Asel support to the DMA driver

[Sascha Hauer]

This adds Asel aka "Address select" handling to the K3 DMA driver.

Asel is a four bit field that has to be put in bits 48-51 of the DMA
addresses. This is needed once the DDR firewalls are enabled.

The DDR firewalls are needed to protect the OP-TEE memory from accesses
from the normal world. One would assume that upstream OP-TEE does this
by default, but apparently it doesn't and once they are enabled ethernet
in barebox stops working. This series fixes networking in barebox with
DDR firewalls enabled.
