This series enables sa2ul support for TI SoC AM64X.
It is based on another series posted by Suman Anna:
<https://lore.kernel.org/linux-arm-kernel/[email protected]/>
rng node has been dropped due to its indirect access from OP-TEE.
Since the sa2ul hardware is being used by OP-TEE as well,
it should be requested using shared TI-SCI flag. So the flag
has been changed from TI-SCI-EXCLUSIVE to TI-SCI-SHARED.
I have tried crypto tests on my local setup, and tcrypt and
self-tests are passing.

From: Suman Anna <[email protected]>
Add the address space for the SA2UL in MAIN domain to the ranges property
of the cbass_main interconnect node so that the addresses within the
corresponding sram nodes and its children can be translated properly by
the relevant OF address API.

See thread: https://lore.kernel.org/all/[email protected]/
lets be consistent as to having the RNG node with disable and logic for
doing the same.
