ram: rockchip: Add initial Kconfig Right now sdram drivers in rockchip SoC are built based on the SoC configs which may not be an adequate solutions while adding common or debug driver. So, add meaningful Kconfig options start with rk3399. Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> Reviewed-by: Kever Yang <Kever.yang@rock-chips.com>

ram: rockchip: Add debug sdram driver Add sdram driver to handle debug across rockchip SoCs. This would help to improve code debugging feature for sdram drivers in rockchip family, whoever wants to debug the driver should call these core debug code on their respective platform sdram drivers.

This enables debugging ram driver API's for the platforms
based on Rockchip SoCs.
This is an option for developers to understand the ram drivers
initialization, configurations and etc.
ram: rockchip: px30: add a config-based ddr selection The SRAM on the PX30 is not big enough to hold multiple DDR configs so it needs to be selected during build. So far simply the DDR3 config was always selected and getting DDR4 or LPDDR2/3 initialized would require a code modification. So add Kconfig options similar to RK3399 to allow selecting the DDR4 and LPDDR2/3 options instead, while DDR3 stays the default as before.
