[PATCH v4 0/2] socfpga: support suspend to ram

[Alan Tull]

Support suspend to ram on socfpga.
  * allocate space in ocram using sram driver.
  * Add a function in ocram to place DDR in self-refresh
    and suspend.
  * SDRAM ECC is mutually exclusive with using ocram for
    suspend, so disable SDRAM ECC if socfpga suspend is
    enabled.
  * Add a device tree binding document for the Altera
    SOCFPGA SDRAM controller that is used to put DDR in
    self-refresh mode.
