This allows drivers to be provided for SDRAM and other RAM
|
|
controllers and their type to be specified in the board's device

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.
