Enable use of the generic atomic64 implementation on AVR32 platforms. Without this the kernel fails to build as the architecture does not provide its version.

AVR32 is a high-performance 32-bit RISC microprocessor core,
|
|
designed for cost-sensitive embedded applications, with particular
|
|
emphasis on low power consumption and high code density.
|
|
|
|
There is an AVR32 Linux project with a web page at

|
The Hammerhead platform is built around an AVR32 32-bit microcontroller from Atmel.
|
|
It offers versatile peripherals, such as ethernet, usb device, usb host etc.
|
|
|
|
The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
|
|
Device (PD).
|
|
|
|
Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
|
|
mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
|
|
will cover even the most exceptional need of memory bandwidth. Together with the onboard
|
|
video decoder the board is ready for video processing.

Merisc is the family name for a range of AVR32-based boards.
|
|
|
|
The boards are designed to be used in a man-machine
|
|
interfacing environment, utilizing a touch-based graphical
|
|
user interface. They host a vast range of I/O peripherals as
|
|
well as a large SDRAM & Flash memory bank.
