Subject: [PATCH v2 0/2] socfpga: fix hotplug/add suspend to ram

From: Alan Tull <atull@...nsource.altera.com>

Patch 1: socfpga: hotplug: put cpu1 in wfi
  Fix how cpu1 is hotplugged to prevent increased power
  consumption.

v2: no need to flush the caches
    clean up spacing in comments
    replace a register offset with a macro

Patch 2: socfpga: support suspend to ram
  * allocate space in ocram
  * Add a function to do suspend to ram and
    place DDR in self-refresh
  * This function lives in ocram

v2: use Generic on-chip SRAM driver to allocate ocram
    rm fncpy_align since generic allocator handles alignment
    check __arm_ioremap_exec return code
    check for NULL pointers
    add a comment regarding sdram controller configuration
