86169cdcb0 rockchip: Fix incorrect constant name in RAM init code
A condition in the rk3399 RAM initialization code used the old
CONFIG_RAM_RK3399_LPDDR4 constant name. This commit changes the
condition to use the correct CONFIG_RAM_ROCKCHIP_LPDDR4 constant.

6e7df1d151 global: Finish CONFIG -> CFG migration
At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks.  Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

The new 32bit DDR controller for TI's am62a family of SoCs shares much

This patch consists mostly of header/macro renames and additions with a
new Kconfig option (K3_AM62A_DDRSS) allowing us to select these new
macros during compilation.

- change RTT_WR from 120 ohm to disable (MR2[11:9])
- change PHY ODT from 40 ohm to 80 ohm (0x1e6e0130[10:8])

Note1: Both DDR-PHY and DDR controller have their own registers for DDR4
Mode Registers (MR0~MR6).  This patch introduces macros to synchronize

581df347db ram: ast2600: Fix incorrect statement of the register polling
The condition "~data" in the if-statement is a typo.  The original
intention is to poll if SDRAM_PHYCTRL0_INIT bit equals to 0. So use
"data == 0" for instead.

Besides, the bit[1] of "phy_status" register is hardwired to
SDRAM_PHYCTRL0_INIT (with inverse logic). Since SDRAM_PHYCTRL0_INIT has
already done, remove the unnecessary checking of phy_status[1].

Currently the default initialisation frequency is 50MHz.  Although
this does appear to be suitable for some LPDDR4 RAM chips, training at
this low frequency has been seen to cause Column errors, leading to
Capacity check errors on others.

Here we force RAM initialisation to happen at 400MHz before ramping up
to the final value running value of 800MHz after everything has been
successfully configured.

  Pin-to-pin compatible options for single and quad core are available.
* Cortex-M4F for general-purpose or safety usage.
* Dual display support, providing 24-bit RBG parallel interface and
  OLDI/LVDS-4 Lane x2, up to 200MHz pixel clock support for 2K display
  resolution.
* Selectable GPUsupport, up to 8GFLOPS, providing better user experience
  in 3D graphic display case and Android.
* PRU(Programmable Realtime Unit) support for customized programmable
  interfaces/IOs.
* Integrated Giga-bit Ethernet switch supporting up to a total of two
  external ports (TSN capable).
* 9xUARTs, 5xSPI, 6xI2C, 2xUSB2, 3xCAN-FD, 3x eMMC and SD, GPMC for
  NAND/FPGA connection, OSPI memory controller, 3xMcASP for audio,
  1x CSI-RX-4L for Camera, eCAP/eQEP, ePWM, among other peripherals.
* Dedicated Centralized System Controller for Security, Power, and
  Resource Management.
* Multiple low power modes support, ex: Deep sleep,Standby, MCU-only,
  enabling battery powered system design.

AM625 is the first device of the family. Add DT bindings for the same.

71eb527476 ram: k3-ddrss: Rename ddrss_ss_regs to ddrss_ctl_regs
The current address being read from dt actually represents the ddrss_ctl
memory region, while ddrss_ss region is something else. Introduce
ddrss_ctl_regs and use it to free up ddrss_ss_regs for its proper
purpose later so that we can avoid confusion.

861682b596 rockchip: ram: sdram_rk3x88: replace comma by semicolon
A comma at the end of a line gives sometimes strange
effects in combination with some code formatters,
so replace a comma by a semicolon in the sdram_rk3188.c
and sdram_rk3288.c files.

0d44ad8bb4 ram: stm32mp1: Unconditionally enable ASR
Enable DRAM ASR, auto self-refresh, unconditionally. This saves non-trivial
amount of power both at runtime and in suspend (on 2x W632GU6NB-15 ~150mW).

5bb26a59c4 ram: aspeed: Rework kconfig options
Ensure the ASPEED related options are grouped together under the RAM
option when enabling support.

This also makes some minor grammar corrections and renames options so
they present cleanly in menuconfig.

There should be no functional change to the configuration or binary.

a48fc5cc6f ram: k3-ddrss: Add support for configuring MSMC subsystem in case of Multiple DDR subsystems
In Multi DDR subystems with interleaving support, the following needs to
configured,

- interleaving granular size and region
- EMIFs to be enabled
- EMIFs with ecc to be enabled
- EMIF separated or interleaved
- number of cycles of unsuccessful EMIF arbitration to wait before
  arbitrating for a different EMIF port, by default set to 3

Add support for configuring all the above by using a MSMC device
