  59           supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols.
  60           This driver takes care of only LPDDR2 memories presently. The
  61           functions of the driver includes re-configuring AC timing

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

  92           This driver is for the EMIF module available on Texas Instruments
  93           AM33XX and AM43XX SoCs and is required for PM. Certain parts of
  94           the EMIF PM code must run from on-chip SRAM late in the suspend
