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. |
