  44           This driver is for the AEMIF module available in Texas Instruments
  45           SoCs. AEMIF stands for Asynchronous External Memory Interface and
  46           is intended to provide a glue-less interface to a variety of
  47           asynchronuous memory devices like ASRAM, NOR and NAND memory. A total
  48           of 256M bytes of any of these memories can be accessed at a given

  56           This driver is for the EMIF module available in Texas Instruments
  57           SoCs. EMIF is an SDRAM controller that, based on its revision,
  58           supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols.
  59           This driver takes care of only LPDDR2 memories presently. The
  60           functions of the driver includes re-configuring AC timing
  61           parameters and other settings during frequency, voltage and
  62           temperature changes

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

  76         help
  77           Enables verbose debugging mostly to decode the bootloader provided
  78           timings. To preserve the bootloader provided timings, the reset
  79           of GPMC is skipped during init. Enable this during development to
  80           configure devices connected to the GPMC bus.
  81
  82           NOTE: In addition to matching the register setup with the bootloader
  83           you also need to match the GPMC FCLK frequency used by the
  84           bootloader or else the GPMC timings won't be identical with the
  85           bootloader timings.

  92           This driver is for the Device Bus controller available in some
  93           Marvell EBU SoCs such as Discovery (mv78xx0), Orion (88f5xxx) and
  94           Armada 370 and Armada XP. This controller allows to handle flash
