  • Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on
    32bit targets.

    GCC can be made to warn about usage of long long types with ISO C90
    (-ansi), but only with -pedantic. You can write this in a way that even
    then it doesn't cause warnings, namely by:

    #ifdef __GNUC__
    __extension__ typedef __signed__ long long __s64;
    __extension__ typedef unsigned long long __u64;
    #endif

    The __extension__ keyword in front of this switches off any pedantic
    warnings for this expression.

  • CONFIG_LBD and CONFIG_LSF are spread into asm/types.h for no particularly
    good reason.

    Centralising the definition in linux/types.h means that arch maintainers
    don't need to bother adding it, as well as fixing the problem with
    x86-64 users being asked to make a decision that has absolutely no
    effect.

    The H8/300 porters seem particularly confused since I'm not aware of any
    microcontrollers that need to support 2TB filesystems.

  • 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.
