    help

      This selects the ARM PrimeCell PL172 MultiPort Memory Controller.

      If you have an embedded system with an AMBA bus and a PL172

      controller, say Y or M here.

    help

      This driver is for Atmel SDRAM Controller or Atmel Multi-port

      DDR-SDRAM Controller available on Atmel AT91SAM9 and SAMA5 SoCs.

      Starting with the at91sam9g45, this controller supports SDR, DDR and

      LP-DDR memories.

      Driver for Atmel EBI controller.

      Used to configure the EBI (external bus interface) when the device-

      tree is used. This bus supports NANDs, external ethernet controller,

      SRAMs, ATA devices, etc.

    help

      This driver is for the AEMIF module available in Texas Instruments

      SoCs. AEMIF stands for Asynchronous External Memory Interface and

      is intended to provide a glue-less interface to a variety of

      asynchronuous memory devices like ASRAM, NOR and NAND memory. A total

      of 256M bytes of any of these memories can be accessed at a given

      time via four chip selects with 64M byte access per chip select.

    depends on ARCH_OMAP2PLUS

    select DDR

    help

      This driver is for the EMIF module available in Texas Instruments

      SoCs. EMIF is an SDRAM controller that, based on its revision,

      supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols.

      This driver takes care of only LPDDR2 memories presently. The

      functions of the driver includes re-configuring AC timing

      parameters and other settings during frequency, voltage and

      temperature changes
