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 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.

|
|
SDRAM devices connected to DDR subsystem.
