  32           This driver is for the AEMIF module available in Texas Instruments
  33           SoCs. AEMIF stands for Asynchronous External Memory Interface and
  34           is intended to provide a glue-less interface to a variety of
  35           asynchronuous memory devices like ASRAM, NOR and NAND memory. A total
  36           of 256M bytes of any of these memories can be accessed at a given
  37           time via four chip selects with 64M byte access per chip select.

  43         help
  44           This driver is for the EMIF module available in Texas Instruments
  45           SoCs. EMIF is an SDRAM controller that, based on its revision,
  46           supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols.
  47           This driver takes care of only LPDDR2 memories presently. The
  48           functions of the driver includes re-configuring AC timing
  49           parameters and other settings during frequency, voltage and
  50           temperature changes

  56           This driver is for the General Purpose Memory Controller (GPMC)
  57           present on Texas Instruments SoCs (e.g. OMAP2+). GPMC allows
  58           interfacing to a variety of asynchronous as well as synchronous
  59           memory drives like NOR, NAND, OneNAND, SRAM.

  64         help
  65           Enables verbose debugging mostly to decode the bootloader provided
  66           timings. To preserve the bootloader provided timings, the reset
  67           of GPMC is skipped during init. Enable this during development to
  68           configure devices connected to the GPMC bus.
  69
  70           NOTE: In addition to matching the register setup with the bootloader
  71           you also need to match the GPMC FCLK frequency used by the
  72           bootloader or else the GPMC timings won't be identical with the
  73           bootloader timings.

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

  90           This driver is for the Memory Controller(MC) module available
  91           in Tegra20 SoCs, mainly for a address translation fault
  92           analysis, especially for IOMMU/GART(Graphics Address
  93           Relocation Table) module.

  99           Say Y for reporting of errors from the Freescale CoreNet
 100           Coherency Fabric.  Errors reported include accesses to
 101           physical addresses that mapped by no local access window
 102           (LAW) or an invalid LAW, as well as bad cache state that
 103           represents a coherency violation.
