   9           This option allows to enable specific memory controller drivers,
  10           useful mostly on embedded systems.  These could be controllers
  11           for DRAM (SDR, DDR), ROM, SRAM and others.  The drivers features
  12           vary from memory tuning and frequency scaling to enabling
  13           access to attached peripherals through memory bus.

  62           This driver provides access to the DPFE interface of Broadcom
  63           STB SoCs. The firmware running on the DCPU inside the DDR PHY can
  64           provide current information about the system's RAM, for instance
  65           the DRAM refresh rate. This can be used as an indirect indicator
  66           for the DRAM's temperature. Slower refresh rate means cooler RAM,
  67           higher refresh rate means hotter RAM.

 124           NOTE: In addition to matching the register setup with the bootloader
 125           you also need to match the GPMC FCLK frequency used by the
