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.

help
|

This allows drivers to be provided for SDRAM and other RAM
|
|
controllers and their type to be specified in the board's device
|
|
tree. Generally some parameters are required to set up the RAM and
|
|
the RAM size can either be statically defined or dynamically
|
|
detected.

The RAM subsystem adds a small amount of overhead to the image.
|
|
If this is acceptable and you have a need to use RAM drivers in
|
|
SPL, enable this option. It might provide a cleaner interface to
|
|
setting up RAM (e.g. SDRAM / DDR) within SPL.
