  Atmel: move console default platform_device to serial driver
  ARM: at91: merge SRAM Memory banks thanks to mirroring
  ARM: at91: finally drop at91_sys_read/write
  ARM: at91/rtc-at91sam9: pass the GPBR to use via resources
  ARM: at91:rtc/rtc-at91sam9: ioremap register bank
  ARM: at91/rtc-at91sam9: each SoC can select the RTT device to use
  ARM: at91/PMC: make register base soc independent
  ARM: at91/PMC: move assignment out of printf
  ARM: at91/pm_slowclock: add runtime detection of memory contoller
  ARM: at91: make sdram/ddr register base soc independent
  ARM: at91: move at91rm9200 sdramc defines to at91rm9200_sdramc.h
  ARM: at91/pm_slowclock: function slow_clock() accepts parameters
  ARM: at91/pm_slowclock: rename register to named define
  ARM: at91/ST: remove not needed casts
  ARM: at91: make ST (System Timer) soc independent
  ARM: at91: make matrix register base soc independent
  ARM: at91/at91x40: remove use of at91_sys_read/write

Based on top of the at91/9x5, rmk/for-armsoc, at91/device-board,
at91/pm_cleanup and at91/base.
