2 bool "Enable RAM drivers using Driver Model"
3 depends on DM
4 help
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
8 the RAM size can either be statically defined or dynamically
9 detected.

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.
