  • d617b338b   avr32: fix out-of-range jump in large kernels ... Browse Code »

    This patch fixes following error (for big kernels):

    ---88---

    It comes up when the kernel increases and 'panic()' is too far away to fit in
    the +/- 2MiB range. Which in turn issues from the 21-bit displacement in
    'br{cond4}' mnemonic which is one of the two ways to do jumps (rjmp has just
    10-bit displacement and therefore a way smaller range). This fact was stated
    before in 8d29b7b9f81d6b83d869ff054e6c189d6da73f1f.
    One solution to solve this is to add a local storage for the symbol address
    and just load the $pc with that value.

  • 7a2a74f4b   avr32: setup crt for early panic() ... Browse Code »

    Before the CRT was (fully) set up in kernel_entry (bss cleared before in
    _start, but also not before jump to panic() in no_tag_table case).

    This patch fixes this up to have a fully working CRT when branching to panic()
    in no_tag_table.

    All ARCHs have the same definition of MKIMAGE. Move it to Makefile.lib
    to avoid duplication.

    All ARCHs have similar definitions of cmd_uimage. Place a sufficiently
    parameterized version in Makefile.lib to avoid duplication.

  • 0430fb20a   [PATCH] AVR32: Minor Makefile cleanup ... Browse Code »

    Don't generate listing by default, remove unused LIBGCC variable and
    rename generated disassembly and listing files to vmlinux.{s,lst}.

    Also make sure that files generated during the build are actually
    removed with make clean.

  • 5f97f7f94   [PATCH] avr32 architecture ... Browse Code »

    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.
