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