This patchset introduces support for secondary cores on tegra30. It also
introduces some functions for the flowcontroller and adds basic support for
tegra30 powerdomains.

---

This patchset requires http://www.spinics.net/lists/arm-kernel/msg158016.html
for the cortex A9 erratum #743622 workaround

Changes in v3:

 * split out chip id changes in several patches
 * remove reset handler debugging code
 * remove unused size declartion for reset SRAM code
 * remove workaround for cortex A9 erratum #743622. This will be handled by
   generic code.

Changes in v2:

 * moved chip id reading to fuse.c and cleanup code
 * don't set bit 1 of SB_CTRL on Tegra20
 * removed unused variables in tegra_cpu_reset_handler_init()

Peter De Schrijver (10):
  ARM: tegra: cleanup use of chipid register
  ARM: tegra: export Tegra chipid
  ARM: tegra: initialize Tegra chipid early
  ARM: tegra: functions to access the flowcontroller
  ARM: tegra: rework Tegra secondary CPU core bringup
  ARM: tegra: prepare powergate.c for multiple variants
  ARM: tegra: export tegra_powergate_is_powered()
  ARM: tegra: add support for Tegra30 powerdomains
  ARM: tegra: support for Tegra30 CPU powerdomains
  ARM: tegra: support for secondary cores on Tegra30
