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

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

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

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

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

 111           Coherency Fabric.  Errors reported include accesses to
 112           physical addresses that mapped by no local access window
