This patch drops support for AVR32 architecture from the Linux kernel.
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.

Pull MMC update from Chris Ball:
"MMC highlights for 3.10:
Core:
- Introduce MMC_CAP2_NO_PRESCAN_POWERUP to allow skipping
mmc_power_up() at boot/initialization time if it's already
happened, for performance (faster boot time) reasons.
- Fix a bit width test failure that resulted in old eMMC cards being
put into 1-bit mode when 4-bit mode was available.
- Expose fwrev/hwrev for MMCv4 parts.
- Improve card removal logic in the case where the card's removed
slowly; we were missing card removal events if the card retained
contact with the slot pads for long enough to reply to a CMD13
while being removed.
Drivers:
- davinci_mmc: Support using PIO instead of DMA.
- dw_mmc: Add support for Exynos4412.
- mxcmmc: DT support, use slot-gpio API.
- mxs-mmc: Add broken-cd/cd-inverted/non-removable DT property
support.
- sdhci-sirf: New sdhci-pltfm driver for CSR SiRF SoCs:
SiRFprimaII: unicore ARM Cortex-A9
SiRFatlas6: unicore ARM Cortex-A9
SiRFmarco: dual core ARM Cortex-A9 SMP
- sdhci-tegra: Add support for Tegra114 platforms, use

Fix regression introduced by commit 796211b7953 ("mmc: atmel-mci: add
pdc support and runtime capabilities detection") which removed the need
for CONFIG_MMC_ATMELMCI_DMA but kept the Kconfig-entry as well as the
compile guards around dma_release_channel() in remove(). Consequently,
DMA is always enabled (if supported), but the DMA-channel is not
released on module unload unless the DMA-config option is selected.
Remove the no longer used CONFIG_MMC_ATMELMCI_DMA option completely.

In the defconfigs for ATNGW100 and ATSTK100[236] the DMA Test driver is
compiled as a module. This means systems built with *_defconfig +
CONFIG_MODULES=n are unusable as the 3 dma test channels monopolise the
CPU.
I 'spose Haavard uses this module a lot but IMO it isn't really
something needed on all eval boards by default.

The Hammerhead platform is built around a AVR32 32-bit microcontroller
from Atmel. It offers versatile peripherals, such as ethernet, usb
device, usb host etc.
The board also incooperates a power supply and is a Power over Ethernet
(PoE) Powered Device (PD).
Additonally, 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.
This patch does include the basic support for the fpga device driver,
but not the device driver itself.

This patch lets the user enable support for EVKLCD100 and EVKLCD101
(refered to by EVKLCD10X). By enabling EVKLCD10X support the LCD
controller and AC97 controller platform devices are added.
The user can also choose between the EVKLCD100 (QVGA display) and the
EVKLCD101 (VGA display), this is added to automagically select the
correct panel timing and resolution parameters.
Enabling support for EVKLCD10X addon board will cripple the MCI platform
device a bit since they share two GPIO lines (detect and write-protect).
These two lines are disabled when EVKLCD10X is enabled.
The default configurations are based upon ATNGW100, but with added AC97C
and LCDC driver. Virtual terminal is also enabled by default for
EVKLCD10X boards.
Verified on hardware with a NGW100 + EVKLCD100/101.

This adds support for the Atmel AVR32 architecture as well as the AT32AP7000
CPU and the AT32STK1000 development board.
AVR32 is a new high-performance 32-bit RISC microprocessor core, designed for
cost-sensitive embedded applications, with particular emphasis on low power
consumption and high code density. The AVR32 architecture is not binary
compatible with earlier 8-bit AVR architectures.
The AVR32 architecture, including the instruction set, is described by the
AVR32 Architecture Manual, available from
http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf
The Atmel AT32AP7000 is the first CPU implementing the AVR32 architecture. It
features a 7-stage pipeline, 16KB instruction and data caches and a full
Memory Management Unit. It also comes with a large set of integrated
peripherals, many of which are shared with the AT91 ARM-based controllers from
Atmel.
Full data sheet is available from
http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf
while the CPU core implementation including caches and MMU is documented by
the AVR32 AP Technical Reference, available from
http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf
Information about the AT32STK1000 development board can be found at
http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918
including a BSP CD image with an earlier version of this patch, development
tools (binaries and source/patches) and a root filesystem image suitable for
booting from SD card.
Alternatively, there's a preliminary "getting started" guide available at
http://avr32linux.org/twiki/bin/view/Main/GettingStarted which provides links
to the sources and patches you will need in order to set up a cross-compiling
environment for avr32-linux.
This patch, as well as the other patches included with the BSP and the
toolchain patches, is actively supported by Atmel Corporation.
