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
  	bool "Enable RAM support in SPL"
  	depends on RAM && SPL_DM
  	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.
  
  config 2GB_LPDDR4
         	bool "SMARC-iMX8M with 16Gb LPDDR4 Memory"
         	help
            Select this if the board is SMARC-iMX8M-D/L/Q-2G
  
  config 4GB_LPDDR4
         	bool "SMARC-iMX8M with 32Gb LPDDR4 Memory"
         	help
            Select this if the board is SMARC-iMX8M-D/L/Q-4G

  config TPL_RAM
  	bool "Enable RAM support in TPL"
  	depends on RAM && TPL_DM
  	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
  	  TPL, enable this option. It might provide a cleaner interface to
  	  setting up RAM (e.g. SDRAM / DDR) within TPL.
  
  config STM32_SDRAM
  	bool "Enable STM32 SDRAM support"
  	depends on RAM
  	help
  	  STM32F7 family devices support flexible memory controller(FMC) to
  	  support external memories like sdram, psram & nand.
  	  This driver is for the sdram memory interface with the FMC.
