From Simon Horman:
Renesas ARM based SoC lager board updates for v3.10

* Use r8a7790 timer setup code to force the
  arch timer to be enabled regardless of the bootloader setting
  - This is necessary for the lager board to boot

This pull request is based on:
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git renesas-boards3-for-v3.10
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git renesas-soc-r8a7790-for-v3.10

The merge was made to provide the r8a7790 timer setup code

* tag 'renesas-boards-lager-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  ARM: shmobile: use r8a7790 timer setup code on Lager
  ARM: shmobile: force enable of r8a7790 arch timer
  ARM: shmobile: Add second I/O range for r8a7790 PFC
