arm: am654: Add r5 support for am654-evm
Subsystems (2)
v2 cover arm: am654: Add r5 support for am654-evm
This series adds r5 build support for booting am654 evm.
There is still 1 step(loading system firmware) missing to complete the full boot. This will be posted as a separate series.
Changes since v1:
- Fixed SPDX headers in patch 1/10
- Updated Linux tag from which dts got synced.
- Updated Reviewed-by tags

PATCH v2 1/10 ram: Introduce K3 AM654 DDR Sub System driver
K3 based AM654 devices has DDR memory subsystem that comprises Synopys DDR controller, Synopsis DDR phy and wrapper logic to intergrate these blocks into the device. This DDR subsystem provides an interface to external SDRAM devices. Adding support for the initialization of the external SDRAM devices by configuring the DDRSS registers and using the buitin PHY routines.
