Add the sdram driver for PX30 to support ddr3, ddr4, lpddr2 and lpddr3. For TPL_BUILD, the driver implement full dram init and without DM support due to the limit of internal SRAM size. For SPL and U-Boot proper, it's a simple driver with dm for get dram_info like other SoCs. Signed-off-by: YouMin Chen <cym@rock-chips.com> Signed-off-by: Kever Yang <kever.yang@rock-chips.com>

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.

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.

|
support external memories like sdram, psram & nand.

Synopys DDR controller, Synopsis DDR phy and wrapper logic to
|
|
intergrate these blocks into the device. This DDR subsystem

|
wrapper logic to integrate these blocks in the device. The DDR
|
|
subsystem is used to provide an interface to external SDRAM
|
|
devices which can be utilized for storing program or data.
|

Enabling this config adds support for the DDR memory controller
|
|
on J721E family of SoCs.
