Simon Glass 6c51df6859 dm: Add support for RAM drivers
Add support for a driver which sets up DRAM and can return information about
the amount of RAM available. This is a first step towards moving RAM init
to driver model.

config RAM
bool "Enable RAM drivers using Driver Model"
depends on DM
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.
config SPL_RAM_SUPPORT
bool "Enable RAM support in SPL"
depends on RAM
help
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.
