Merge branch 'marco-timer-cleanup-rebase' of git://gitorious.org/sirfprima2-kernel/sirfprima2-kernel into next/soc

From Barry Song, this adds support for a new SoC from CSR; marco. It's
SMP, uses GIC instead of VIC and in general needs a bit of rework of
the platform code for setup, which this branch contains.

* 'marco-timer-cleanup-rebase' of git://gitorious.org/sirfprima2-kernel/sirfprima2-kernel:
  ARM: PRIMA2: provide two DEBUG_LL ports for prima2 and marco
  ARM: PRIMA2: add new SiRFmarco SMP SoC infrastructures
  ARM: PRIMA2: irq: make prima2 irq can work even we enable GIC for Marco
  ARM: PRIMA2: rtciobg: it is also compatible with marco
  ARM: PRIMA2: rstc: enable the support for Marco
  ARM: PRIMA2: mv timer to timer-prima2 as we will add timer-marco
  ARM: PRIMA2: initialize l2x0 according to mach from DT
  ARM: PRIMA2: enable AUTO_ZRELADDR for SIRF in Kconfig
  ARM: PRIMA2: add CSR SiRFmarco device tree .dts
