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"
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.
38 bool "Enable MPC83XX SDRAM support"
41 Enable support for the internal DDR Memory Controller of the MPC83xx
42 family of SoCs. Both static configurations, as well as configuring
43 the RAM through the use of SPD (Serial Presence Detect) is supported
44 via device tree settings.
47 bool "Enable AM654 DDRSS support"
48 depends on RAM && SOC_K3_AM6
50 K3 based AM654 devices has DDR memory subsystem that comprises
51 Synopys DDR controller, Synopsis DDR phy and wrapper logic to
52 intergrate these blocks into the device. This DDR subsystem
53 provides an interface to external SDRAM devices. Enabling this
54 config add support for the initialization of the external
55 SDRAM devices connected to DDR subsystem.
58 bool "Enable J721E DDRSS support"
61 The J721E DDR subsystem comprises DDR controller, DDR PHY and
62 wrapper logic to integrate these blocks in the device. The DDR
63 subsystem is used to provide an interface to external SDRAM
64 devices which can be utilized for storing program or data.
65 Enabling this config adds support for the DDR memory controller
66 on J721E family of SoCs.
69 bool "Enable i.MXRT SDRAM support"
72 i.MXRT family devices support smart external memory controller(SEMC)
73 to support external memories like sdram, psram & nand.
74 This driver is for the sdram memory interface with the SEMC.
