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.
