5	  This allows drivers to be provided for SDRAM and other RAM
6	  controllers and their type to be specified in the board's device
7	  tree. Generally some parameters are required to set up the RAM and

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