  [AVR32] Add missing #include <linux/module.h>
  [AVR32] ssize_t should be long, not int
  [AVR32] Remove last remains of libgcc
  [AVR32] SPI platform code update
  [AVR32] Add PIOE device and reserve SDRAM pins
  [AVR32] Introduce at32_reserve_pin()
  [AVR32] Don't reset PIO state at bootup
  [AVR32] GPIO API implementation
  [AVR32] Use ARRAY_SIZE macro when appropriate
  [AVR32] Implement dma_mapping_error()
  [AVR32] Fix incorrect invalidation of shared cachelines
  [AVR32] ext int fixes
  [AVR32] fix serial port setup on ATSTK1000
