2 bool "Enable RAM drivers using Driver Model"
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
12 bool "Enable RAM support in SPL"
13 depends on RAM && SPL_DM
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.
21 bool "Enable RAM support in TPL"
22 depends on RAM && TPL_DM
24 The RAM subsystem adds a small amount of overhead to the image.
25 If this is acceptable and you have a need to use RAM drivers in
26 TPL, enable this option. It might provide a cleaner interface to
27 setting up RAM (e.g. SDRAM / DDR) within TPL.
30 bool "Enable STM32 SDRAM support"
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.
