   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.

  11 config SPL_RAM

  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.

  20 config TPL_RAM
  21         bool "Enable RAM support in TPL"

  33           STM32F7 family devices support flexible memory controller(FMC) to
  34           support external memories like sdram, psram & nand.
  35           This driver is for the sdram memory interface with the FMC.
