Commit 2dbf3d5c authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/egtvedt/linux-avr32

Pull AVR32 removal from Hans-Christian Noren Egtvedt:
 "This will remove support for AVR32 architecture from the kernel and
  clean away the most obvious architecture related parts. Removing dead
  code in drivers is the next step"

Notes from previous discussion about this:
 "The AVR32 architecture is not keeping up with the development of the
  kernel, and since it shares so much of the drivers with Atmel ARM SoC,
  it is starting to hinder these drivers to develop swiftly.

  Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now
  Microchip).

  Finally, the GCC toolchain is stuck at version 4.2.x, and has not
  received any patches since the last release from Atmel;
  4.2.4-atmel.1.1.3.avr32linux.1.

  When building kernel v4.10, this toolchain is no longer able to
  properly link the network stack.

  Haavard and I have came to the conclusion that we feel keeping AVR32
  on life support offers more obstacles for Atmel ARMs, than it gives
  joy to AVR32 users. I also suspect there are very few AVR32 users left
  today, if anybody at all"

That discussion was acked by Andy Shevchenko, Boris Brezillon, Nicolas
Ferre, and Haavard Skinnemoen.

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
http://avr32linux.org/.

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

well as a large SDRAM & Flash memory bank.

This choice disables the detect pin and the write-protect pin for the

The MCI pins can be reenabled by editing the "add device function" but
this may break the setup for other displays that use these pins.

Specify the target rate the internal DAC should try to match. This
will use PLL1 to generate a frequency as close as possible to this
rate.
Must be within the range 32000 to 50000, which should be suitable to
generate most other frequencies in power of 2 steps.
Ex:
48000 will also suit 24000 and 12000
44100 will also suit 22050 and 11025
32000 will also suit 16000 and 8000

This adds support for the Cyclone III FPGA from Altera
found on Miromico's Hammerhead board.
Choose 'Y' here if you want to have FPGA support enabled.
You will have to choose the "Hammerhead FPGA Device Support" in
Device Drivers->Misc to be able to use FPGA functionality.
