- 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.

- depends on (ARCH_DAVINCI || ARCH_KEYSTONE) && OF
- 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.
- config TI_EMIF

- 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
- config MVEBU_DEVBUS
- bool "Marvell EBU Device Bus Controller"

- help
- This driver is for the Device Bus controller available in some
- Marvell EBU SoCs such as Discovery (mv78xx0), Orion (88f5xxx) and
- Armada 370 and Armada XP. This controller allows to handle flash
- devices such as NOR, NAND, SRAM, and FPGA.
- config TEGRA20_MC

- depends on ARCH_TEGRA_2x_SOC
- help
- This driver is for the Memory Controller(MC) module available
- in Tegra20 SoCs, mainly for a address translation fault
- analysis, especially for IOMMU/GART(Graphics Address
- Relocation Table) module.
- config TEGRA30_MC
- bool "Tegra30 Memory Controller(MC) driver"
- default y
- depends on ARCH_TEGRA_3x_SOC
- help
- This driver is for the Memory Controller(MC) module available
- in Tegra30 SoCs, mainly for a address translation fault
- analysis, especially for IOMMU/SMMU(System Memory Management
- Unit) module.
- config FSL_CORENET_CF
- tristate "Freescale CoreNet Error Reporting"
- depends on FSL_SOC_BOOKE
- help
- Say Y for reporting of errors from the Freescale CoreNet
- Coherency Fabric. Errors reported include accesses to
- physical addresses that mapped by no local access window
- (LAW) or an invalid LAW, as well as bad cache state that
- represents a coherency violation.

- This driver is for the Memory Controller module in MediaTek SoCs,
- mainly help enable/disable iommu, help control the power-domain and
- the clocks for each local arbiter. It also help bandwidth control
- for different scenario.
- config MTK_SMI_V1
- bool "MTK SMI V1"
- depends on ARCH_MEDIATEK || COMPILE_TEST
- help
- This driver is for Mediatek SMI verion-1 which have smi_common_ao
- base. It will enable/disable iommu, help control the power-domain and
